Lego Combination Safe

Do you need a place to store your money, but you don't want to spend a lot on a strongbox? Then try this lego version, it's a little less theft-proof than a real one, but it comes close.

I've seen a few combination safes on youtube, but they all used an at least 5 times bigger mechanism than this one. So if you build this safe you have less chance to run out of lego bricks before you're finished.

IMPORTANT: Before you decide to build this, look at the second picture below! Those are the fancy pieces needed. The first, the nine curved bricks, are absolutely required, but not necessarily in red. The two springs, are not extremely important; without it, the door doesn't 'jump' open as you can see in the video below. All other pieces I used, are common lego pieces which belong in an average lego collection, or are well replaceable by a surrogate.


So if you decide to build it, proceed to the next step!

1: A round brick. Take three of these, as you can see in the bottom of the image. Each will be a rotor, number them 1,2, and 3, because later on, we'll treat each one different.
2: Place three curved bricks around it, leaving a gap which will be the rotor's notch.
3: A 4x4 plate on top of it.
4: Another round brick, on top of the plate.
5: Cover the rest with tiles.
6: Another plate, on top of the round brick, only for rotor 1 and 2.
7: Now place a 1x1 round brick on the top plate, the place of it will influence the number sequence of your safe. See the next image, an animated gif, to learn where you can put it.
8: Rotor 2 should be exactly like this. Rotor 3 aswell, but without the plate plus 1x1 round brick at the end. For rotor 1 you only need to add the two round plates at the beginning, without the stuff sticked in them.

Thus the problem remains: legos come apart. :P
someguyfromUK in reply to Infinite_minus_zeroMar 8, 2012. 9:29 AM
Just use a hot glue gun to stick the casing together. That's what the proffesional lego artists and people @ lego land do...
jobard in reply to Infinite_minus_zeroAug 10, 2011. 7:19 AM
This is not supposed to be really "safe". I wouldn't put anything valuable inside it, but it's a great gadget
Infinite_minus_zero in reply to jobardAug 10, 2011. 8:56 AM
haha, ya. or maybe you could glue the pieces together.
pickle5 says: Jul 6, 2011. 9:47 AM
i have like a TON of parts but not the right ones for any lego instructables
skolsox in reply to pickle5Dec 10, 2011. 7:03 AM
you can order individual pieces on the cheap form lego.com under pick a brick
ipwnupeep says: Dec 24, 2010. 5:45 PM
id just get a hammer and smash the whole thing open and jack the money
LegoScorpion381 in reply to ipwnupeepNov 6, 2011. 5:45 AM
Ya funny thing...Still an AMAZING idea
jharvison says: Jul 18, 2011. 4:15 PM
do you think you could add a parts list because its a real pain to go through the whole thing and come up with a list it would be extremely helpful and i hope it wouldnt be to hard to do please reply
merijnvw (author) in reply to jharvisonJul 26, 2011. 4:17 AM
look at the date, I made this intructible more than two years ago. I don't feel like updating it in eternity. I think I already mad it very comprehensible compared to most other lego ibles.
the most important bricks are the curved ones and the technical parts. the rest are regular bricks that you either already have or can find really easily, if not grey then a different colour
jharvison in reply to merijnvwJul 26, 2011. 1:57 PM
im sorry i was kinda in a bad mood when i posted it and now that i look at it i completely agree with you about it being comprehensible and i guess i can just make my own sorry about snapping at you like that i hope that in the future we can have better conversations than this

lego dude 305 says: Jun 25, 2011. 2:23 PM
cool but can you make a mechanism with less of the curve pieces

soccernoodle says: Dec 20, 2010. 12:03 PM
wow this is amazing but i only have 8 of the curved pieces :( i am currently searching for the 9th one. wish me luck!
pie R []ed in reply to soccernoodleMay 15, 2011. 10:49 PM
make it with 1 less rotor...
merijnvw (author) in reply to soccernoodleDec 27, 2010. 8:13 AM
good luck
scistone in reply to merijnvwMay 15, 2011. 11:26 AM
I DON'T HAVE ANY! WAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA!
scistone says: May 15, 2011. 11:27 AM
U think I could make it without using legos?

I don't have some of the peices.
jackerboy says: May 15, 2011. 10:12 AM
i want to make this but i dont have enough peices
atomiclegocreations says: Apr 19, 2011. 10:10 AM
my comment below states that the rotor gets stuck. I mean that the rotor will stop. I guess because it's lose. A good shake or tilting the thing works, so I guess I fixed it. the only problem is constructing the box. I have this little coin dispenser thing and I worked so hard on it that I'm just not willing to destroy it. Would this work as a box?: The base of the locking thing would link with the bottom of the safe, then the top of the lock would be covered up with Legos.
merijnvw (author) in reply to atomiclegocreationsApr 25, 2011. 12:18 PM
Hey man I reasd your comment, I will try to think about it later as now I am on vacation in Berlin and I don't have much time, in a few days I will re-read this, hold on. In the meanwhile good luck!
merijnvw (author) in reply to merijnvwApr 28, 2011. 6:44 AM
Yes it would do I think, I don't have pics but I imagine it would work. You say it would interlink with the lego safe lock through the base. In my version they interlink on the side, but you could also make the lock underneath the 'coin dispenser'. Either way you could rotate the coin dispenser sideways to use it the same way I did. I don't have pics so I can't say much about it, good luck!
atomiclegocreations says: Apr 27, 2011. 3:29 PM
Actually, don't bother to think about it now.

I took it apart to get pieces and now after a LOT of creations I've made a coin bank that can hold a lot of change.

Sorry about that (but hey, now you don't have to think about a loose rotor)

But hey, thanks!
uberdum05 says: Apr 23, 2011. 9:58 AM
I once made a lego safe that used the NXT set and a motor but it was easily defeatable by pushing a phillips head screwdriver into where the motor was located then turning it 90 degrees...
atomiclegocreations says: Apr 18, 2011. 6:08 PM
for some reason, the 2nd rotor (behind the rotor with the dial) gets stuck at a point when it grabs onto the 3rd rotor. I've tried to do something, but it keeps doing it. Could you help?
pgardner says: Apr 9, 2011. 3:47 PM
can i just use bricks to go around the red circle?
merijnvw (author) in reply to pgardnerApr 11, 2011. 10:54 AM
not straight bricks because the pins should rest still on them until they can fall in, so they should have a curve. Or in another way they should make a circle. If you have another method please tell.
Lego man 201 says: Mar 12, 2011. 7:07 AM
This is probaly the easiest thin i've made because my cousin is an awseome lego builder and sent me a whole bag and taught me how to do a lego thing. Pictures coming
dobie354 says: Jan 18, 2011. 5:40 PM
I cannot wait to try probably the hardest (and coolest) thing i have ever made
I made a different version of a safe but it wasn't as cool.
(it didn't have the padlock type thing)

Holland, also called The Netherlands
nfk11 says: Dec 18, 2010. 7:41 AM
i cant make it because i dont have the pieces
merijnvw (author) in reply to nfk11Dec 20, 2010. 8:33 AM
there are some websites where you can order lego per piece, you can look up if your country has one.

gageylawson says: Sep 26, 2010. 7:29 AM
OMG. I am making this right away.
paperairplanecreator says: Aug 19, 2010. 2:14 PM
oh. em. ge.thats probably the most complex lego creation. EVAR!
freecell64 says: Jul 25, 2010. 11:11 AM
Lol i like it the only issue is i would hate to have it fall tile floors are not nice to legos at all
hhhttt says: Jul 24, 2010. 1:14 PM
very nice photography on the safe. that looks very cool. im working on a new design for mine, a little bit less complicated.
knexguns656 says: Jul 15, 2010. 7:40 PM
I made 1 but i modified it a bit it on regular hinges and to open it u have 2 decode a message then press a brick but its really tricky to find!!
Redgerr says: Jul 8, 2010. 8:16 AM
i just came back to look at this today and still i think this was amamzing.. i was a big lego guy and never imagined that you could do somthing so awsome with a few bricks. you clearly knew your lego and lock's, great 'ible!
meanbean says: Jun 25, 2010. 10:15 AM
I almost ripped my hair out when it said to take almost everything apart to build the walls, but it was well worth it. With some careful analysis, this thing works wonderfully. 5*s!
merijnvw (author) in reply to meanbeanJun 28, 2010. 12:58 PM
Haha sorry about that, I believe I couldn't think of a better order of the steps because it was this or something worse. Thanks and have fun with your safe!
wickedsonic1 says: Jun 28, 2010. 6:56 AM
really nice model but i dont have the bricks
cars2cool says: Jun 21, 2010. 10:14 AM
when u said in step 1.8 that rotor 3 shouldn't have the plate and round 1x1 piece, what did u mean? can u make a picture of all the rotors please.
merijnvw (author) in reply to cars2coolJun 22, 2010. 6:37 AM
Hi, I meant that the last rotor doesn't need to push another rotor. The white plate I use, plus the red small cilinder on it, the pin, should be left away. No I can't make photos of the three rotos because I demolished the safe already (made this Instructable a year ago) good luck
cars2cool in reply to merijnvwJun 24, 2010. 6:20 AM
thanks, i think i get it now, it's a shame that u demolished ur safe, it was a pretty nice piece of work. well, just got to wait until my lego springs in the mail, then, i'll finish it. :)
zixx65 says: Jun 5, 2010. 12:08 PM
hey im wondering..... how big is this creation?
merijnvw (author) in reply to zixx65Jun 6, 2010. 3:58 AM
As you can see on the picture: 16 × 14 lego points on the front, it's about the same in length so not very big.

Kryptonite says: Oct 3, 2009. 1:13 AM
Damn, my step-brother doesn't seem to have all the necessery bits to make this, are there any kits with all the pieces?
merijnvw (author) in reply to KryptoniteOct 3, 2009. 3:57 AM
Sorry, I have no idea and I don't remember where I have the pieces from anymore. but there are certain sites where you can order lego pieces per one.
mashedpotato13 in reply to merijnvwApr 25, 2010. 4:47 PM
Kryptonite in reply to merijnvwOct 3, 2009. 10:34 PM
Hmm, good idea. If you set up a kit with all the pieces I imagine you'd get a fair number of customers. Although, would it be legal to re-sell?
merijnvw (author) in reply to KryptoniteOct 4, 2009. 3:59 AM
Like that, it probably wouldn't, but it is still possible to do legally. On factory.lego.com you can get a program in which you design lego things on the computer and you can publish them there on the site. Then you can order the whole set and others can too. I don't know if you(as the designer) get s share of the incomes, I never tried it. The really succesful models come as sets in real life lego shops, I know for sure that then you will get a share.
Kryptonite in reply to merijnvwOct 5, 2009. 4:55 PM
Wow, I'd recommend it because this really is one crafty piece of work.
micah122 says: Feb 4, 2010. 2:55 PM
cool

InsaneMage says: Feb 4, 2010. 11:19 AM
It may not be as strong as a safe, but just placing it in plain sight in your "toy-room" would have it as one of the safest things ever. Most people won't bother looking there.
drumerdude250 says: Dec 30, 2009. 1:36 PM

Anybody could open it, just step on it and steal his monopoly money!! lol
 

hi111 says: Dec 29, 2009. 9:18 AM
 Is it actually sturdy?
meaning could i drop it from waste height and open it.
merijnvw (author) in reply to hi111Dec 29, 2009. 10:08 AM
 It would break if you drop it from 3m I think
bassclarinet23 says: Dec 12, 2009. 11:12 AM
Awesome! I don't have the pieces, but this is brilliant.
magicman12345 says: Dec 6, 2009. 10:34 AM

If you don't have springs what do you use?
 

merijnvw (author) in reply to magicman12345Dec 7, 2009. 6:26 AM
a rubber band, or nothing and you open the door by yourself
magicman12345 in reply to merijnvwDec 8, 2009. 3:38 PM
Thanks!
lemonpickle says: Nov 22, 2009. 7:33 PM
this is awesome        too bad I don't have some of the pieces
almcgo says: Nov 14, 2009. 5:58 PM
i dont hav the right parts for the hinges on the door and ive tried 5 difrent othr ways but i cant find one that works. can u post another way???
merijnvw (author) in reply to almcgoNov 15, 2009. 4:44 AM
 No because I don't know which parts you do have. You can use regular hinges but they may be too weak, or you could just not use hinges, and make the door thicker so it would be more like a drawer, so it shoves out instead of swinging out.
almcgo says: Nov 12, 2009. 2:36 PM
do the bars have 2 hav holes in them??? im in da mid of makin one
merijnvw (author) in reply to almcgoNov 13, 2009. 4:48 AM
step 2.16: Add more holed bars and 1x4 plates. Not necessarily all bars need to have holes, see step 3.11 and 5.5 to see where there need to be holes, to hold the springs. I'm saying this because if you don't have a lot of holed bars, you don't have a problem. I filled this all with holed bars, because I will need a lot of grey bars without holes on the outside of the safe, and when I use those now, I could run out of un-holed bars when I need them.
almcgo in reply to merijnvwNov 14, 2009. 12:16 PM
o i read dat after the comment lol but does the 3rd rotor have to have the 1x1 peg on top of the 2 round plates or where does the 1x1 brick go on rotor 3??
minime12358 says: Nov 12, 2009. 2:25 PM
" Then try this lego version, it's a little less theft-proof than a real one, but it comes close."

Not if you have 40 billion legos and a nice way to weld an inch thick of steel on to the sides of it (-:
fireruler12 says: Aug 6, 2009. 3:47 PM
where did you get the springs
merijnvw (author) in reply to fireruler12Aug 7, 2009. 2:23 AM
I believe I got some from a lego mindstorms set, but I also have some from other lego technic sets. They're not so rare.
adx00 in reply to merijnvwNov 9, 2009. 1:23 PM
Can you substitute shocks from a lego snomobile???
merijnvw (author) in reply to adx00Nov 9, 2009. 2:48 PM
 I don't know lego snowmobiles so I don't know what psrings it has, but I think you can work that out yourself. If the can psuh you can use them in this, perhaps mount them a little different because of a different length or something.
brickgunsproductions in reply to merijnvwSep 24, 2009. 2:34 PM
can you also do the same with a rubber band?
Killer~SafeCracker says: Nov 8, 2009. 7:31 PM
This is really cool man. I've never really been that good with legos but it looks like you're great. How long did it take to come up with this??
adx00 says: Nov 8, 2009. 5:09 PM
im gonna try to build it but i might need a simpler version
EncasedDeath says: Oct 6, 2009. 3:09 PM
do u have any idea where i can get the fancy legos?
merijnvw (author) in reply to EncasedDeathOct 7, 2009. 7:43 AM
 No sorry, I don't know where I got them from. But you can order lego pieces per piece on some websites.

super awesome, im going to make it as soon as i can
renscan2 says: Jun 30, 2009. 10:06 PM
If someone really wanted to get in couldn't they just smash it? Lol
RedFlash in reply to renscan2Jul 1, 2009. 4:08 PM
Not unless you have a bit of superglue lying around!
Duct Tape Dude in reply to RedFlashSep 15, 2009. 2:55 PM
Exactly 1 drop of hot glue between each outside brick=safer safe
Bartboy in reply to Duct Tape DudeSep 16, 2009. 4:38 AM
Then wrapped in duct tape.....
RedFlash in reply to BartboySep 20, 2009. 6:21 PM
But duct tape can easily be peeled away.
Bartboy in reply to RedFlashSep 21, 2009. 12:30 PM
Not when there is glue under it.......
RedFlash in reply to BartboySep 21, 2009. 4:54 PM
Sorry, I thought that you meant to glue the bricks together instead of gluing the tape to the safe
simfire687 in reply to RedFlashSep 22, 2009. 10:11 AM
simple as a falcon punch
geodez in reply to RedFlashJul 6, 2009. 5:45 PM

dombeef in reply to geodezJul 7, 2009. 11:23 AM
It might break the item inside
Blake380 in reply to RedFlashJul 3, 2009. 8:33 AM
You technically still could though. Plastic is weak.
frodobot in reply to Blake380Jul 5, 2009. 7:31 AM
not necessarily so. plastic can be very very strong
bowmaster in reply to frodobotJul 6, 2009. 6:21 PM
Legos aren't high-explosive shaped charge strong.
frodobot in reply to bowmasterJul 7, 2009. 1:09 PM
pardon? I don't get what you mean
bowmaster in reply to frodobotJul 7, 2009. 2:08 PM
You could break into it (the safe) if you used high explosives.
frodobot in reply to bowmasterJul 8, 2009. 8:58 AM
ahem (obviously, its lego. what i meant is that if lego is structured correctly, if can be very strong and resistant but not bomb-proof (but that would be a very good idea, bomb-proof lego)
merijnvw (author) in reply to frodobotJul 8, 2009. 9:12 AM
Some reactions below this one, atokad33 posted this:
sweet ill have to make this with my metal legos I have a friend that works for a company with a CNC milling machine and he made me a bunch of metal legos at my insistence
So those could be bomb proof!
Grey_Wolfe in reply to merijnvwJul 13, 2009. 11:51 PM
I so thought of metal Legos the instant I saw this. Very awesome design, btw. Favorited. Actually, the plastic used to make Legos and the structure of the pieces makes them incredibly strong when constructed correctly. Sugerglue is pretty fragile, but one could use epoxy to glue the structure together. It's not like any lock on the planet is guaranteed to keep the badies out, but a little extra structure helps keep honest people honest. :)
Blake380 in reply to merijnvwJul 8, 2009. 11:19 AM

stormz76 says: Aug 7, 2009. 8:16 PM
do they need to be smooth or can they have studs on them?
merijnvw (author) in reply to stormz76Aug 8, 2009. 2:41 PM
Well I'm not sure what studs are but I think you mean like grooves and such. All of the bricks in these rotors may have them, maybe except for the curvy bricks, because on those, on the side there are bars that should fall into the gaps, and they may get stuck in the 'studs' if those studs are too big but it probably won't give a problem.
Duct Tape Dude in reply to merijnvwSep 15, 2009. 2:48 PM
Studs are the little round thingies that connect the bricks together usually found on top of the bricks (btw you are a Monopoly Millionare!!!)

mykmykmykkk says: Jul 17, 2009. 6:07 AM
if i wanted your money i would just smash it... awsome mechanism you should make it in metal and it will be a proper safe
TheSolderModder in reply to mykmykmykkkJul 28, 2009. 9:09 PM
I think your missing the point to it. Yes you could just smash it and get what's inside, but the guy build a 3 number combination safe OUT OF LEGOS... So he doesn't need a "proper metal safe" this is just a genius! 5 stars without a doubt.

Great idea and I wanted to build it but didn't have those 9 important parts! So I tried different ways of how to build it and came up with how to get around not having those parts. But the only problem is that it is only a four number combination, replay if you want the design. Anyways great idea.

u probably realise that this is not a safe safe.

sledge hammer + Lego safe + thief = Rubble
mynameinc in reply to Blackbird17Jul 12, 2009. 12:28 PM
You could also say
sledge hammer + Lego safe + thief = Ruble
=P

I would say a thief could get the safe open WITHOUT a sledge hammer, but haven't tried it.
Blackbird17 in reply to mynameincJul 13, 2009. 12:43 AM
pry it open mayhaps?

thanks!
nande says: Jul 7, 2009. 3:57 PM
I have an idea for an improvement, that is, you can use lego pieces to build a cover for the dial and then disguise it as a model of a house or something.. an added layer of security!
merijnvw (author) in reply to nandeJul 7, 2009. 5:18 PM
good idea!
jcomtois says: Jul 7, 2009. 4:49 PM
As a long time Lego user I have to say this is one of the cooler things out there. Not quite Babbage engine cool, but cooler than most.

very well written i would make on but i dont hav any curved pieces where could i get them for cheap?
Blake380 in reply to kdelwatJul 3, 2009. 8:30 AM
You can find them off of this site: shop.lego.com/pab
Cartuner55 in reply to Blake380Jul 3, 2009. 10:06 PM
on the right search for Element ID 4567445
squeakyneb says: Jul 3, 2009. 12:33 AM
I am probably never going to build this, not out of Lego anyway, but it did teach me about the workings of a combo lock. Thanks mate!
knexsuperbuilderfreak says: Jul 2, 2009. 10:40 AM
are the shocks really needed?
merijnvw (author) in reply to knexsuperbuilderfreakJul 2, 2009. 11:41 AM
Is a shock a spring? If that is so, no, they are not absolutely required like the curvy things. The shocks make that the door flies open. Without them, you have to pull open the door by yourself...
knexsuperbuilderfreak in reply to merijnvwJul 2, 2009. 12:40 PM
thnks
Derek Scott Customs says: Jul 2, 2009. 7:16 AM
Great ible it is probably safer if you glue it. What bad guy would search a lego safe? They just want to get in get out
merijnvw (author) in reply to Derek Scott CustomsJul 2, 2009. 11:39 AM
Yup, it's a waste to glue all that lego, but it could be useful to glue some pieces of the rotors, because when you use a little old pieces they can break when turning the dial and you'll have to open the walls again to repair it.
ShoopDaWhoop says: Jul 2, 2009. 9:21 AM

RedFlash says: Jun 30, 2009. 12:50 AM
What website can you find the red curvy thing?
jswilson64 in reply to RedFlashJul 2, 2009. 9:29 AM
Brick Link - www.bricklink.com It's part # 3063, White Brick, Round Corner 2 x 2 Macaroni
Harpes1 in reply to RedFlashJul 1, 2009. 3:32 AM
there is a shop in sa called toy corner and they sell individual lego pieces but they also hav an online shop and they can mail the pieces, have a look at their website and see if they hav the piece you need http://www.toycorner.com.au/
hope this helped
RedFlash in reply to Harpes1Jul 1, 2009. 4:06 PM
Thank You so much!!!!! I have been also looking for a site like this ever since I started playing with lego!!!!!
RedFlash in reply to RedFlashJul 1, 2009. 4:15 PM
There's no pieces and it's in South Australia
merijnvw (author) in reply to RedFlashJun 30, 2009. 1:02 PM
I Here in Holland we have a website called lossestenen.nl where we can order almost all lego bricks per piece, but you live in Australia so I don't know any website of that kind there. You can just search for 'separate lego pieces' or something in your area.
Draxis in reply to merijnvwJul 1, 2009. 1:52 PM
LEGO.com has a pick-a-brick section where you can order most of their bricks for a few cents each, straight from the source, skipping the middle man. This is what I use in the US, so I'm pretty sure it's the same worldwide. the link is here: http://shop.lego.com/PAB/
RedFlash in reply to DraxisJul 1, 2009. 4:07 PM
Tried That, didn't have the curvy bit
beccles123 in reply to RedFlashJul 2, 2009. 4:34 AM
bro, are you sure looked properly at this link? I've just ordered these pieces from this site. Perhaps you should look a little harder, because they are indeed there! Show 500 results per page, hit ctrl+f, type in 'curved' and hit search. They're $0.17AUD a piece.
Draxis in reply to DraxisJul 1, 2009. 2:02 PM
Also, here is a ling to Lego for a program where you make the creation, than the program records the parts and you can choose to purchase them from LEGO online, it is a very nifty program.

http://factory.lego.com/default.aspx
RedFlash in reply to DraxisJul 1, 2009. 4:07 PM
Very clever, but sadly it doesn't have the bricks I want and it costs more
Draxis in reply to RedFlashJul 2, 2009. 5:57 AM
Oh well...
davestorm says: Jul 2, 2009. 9:12 AM

You should try having a play with LEGO Digital Designer ( http://ldd.lego.com/ ) to produce building guides

wow! thats so cool! I wish I had the pieces :-(
guitarmonk15 says: Jul 1, 2009. 6:26 AM
Cool instructable, but do you want to see me break in? (sound of legos being smashed) MWA HA HA HA! now I got my 500 dollars of...... wait a second, OH SH*T! it's monopoly money! (sirens in the distance) But really, nnice 'ible
atokad33 says: Jun 28, 2009. 6:27 PM
sweet ill have to make this with my metal legos I have a friend that works for a company with a CNC milling machine and he made me a bunch of metal legos at my insistence that's awesome btw
mage in reply to atokad33Jun 30, 2009. 12:50 AM
metal legos? do they still connect properly?
merijnvw (author) in reply to atokad33Jun 29, 2009. 7:20 AM
Metal legos??? Never heard of that!
RedFlash says: Jun 29, 2009. 4:00 PM
That is so cool!!!!! Great Instructable!!!!!!!!!!!!! I don't have the peices, but this is going to be a tough nut to build

Wareagle says: Jun 28, 2009. 3:07 PM
wow this thing is really cool! i will attempt to make it, but i don't have the spring parts. is there a way to make it without them?
merijnvw (author) in reply to WareagleJun 28, 2009. 3:12 PM
Yes sure, then you just have to pull the door open by yourself! Or you can take springs from a big pen, with a spring that fits around a black technic stave, and make the spring mechanism yourself.
poparoo4 says: Jun 28, 2009. 9:24 AM
iTS AMAZING but couldn't you just take the bottom off. Maybe glue the peices together?
merijnvw (author) in reply to poparoo4Jun 28, 2009. 3:09 PM
Yes that's true but i don't feel like gueing my legos
shiakazee says: Jun 27, 2009. 8:25 PM
man, this would be really useful for me. when I remember the combo I do the combo, when I forget I can always dismantle the safe and get my own monopoly money =)
raimen in reply to shiakazeeJun 28, 2009. 10:43 AM
lmao xD
klee27x says: Jun 28, 2009. 12:24 AM
This is very neat. I can think of worse ways to spend 2 hours. Can you source all the parts and make a kit with some instructions? Better yet, take your plans to Lego and see if they'll make it. I'd buy one!
dla888 says: Jun 26, 2009. 12:30 PM
But would a burgalar think that you keep real money in a lego safe?

no, and that's the beauty of it.

there should be a glue that was like: duct tape, krazy glue, super glue, elmers glue, elmers wood glue all in a blender. we shall call it Norris glue!
Broom in reply to DELETED_GuardianFoxJun 27, 2009. 7:52 AM
Incorrect. Mastering the ancient art of Lego(tm)-safecracking would be the logical next step... followed by apprehension, a swift but fair trial by 12 Lego(tm) peers, and then 20 years to learn to break out of Lego(tm) jail.
Emsaid says: Jun 26, 2009. 4:33 PM

No offense, but duh.
mikeasaurus says: Jun 26, 2009. 8:45 AM
ahhh....lego, is there anything you can't build? This is a very clever project, ironically not-so-safe considering the material. The true genius is teh use of Monoply money. I like it! Great job!
1up in reply to mikeasaurusJun 26, 2009. 4:53 PM
If you superglued the bricks together, it'd be a lot stronger. ;)
MegaMaker in reply to 1upJun 27, 2009. 7:07 AM
Really?
Broom in reply to MegaMakerJun 27, 2009. 7:48 AM
No. I mean, yes! But I'd use duct tape, cuz I love it so much.

vandalex says: Jun 26, 2009. 8:33 PM
i think its cool, a little super glue, model cement or something might actually make it sort of practical
Arbitror says: Jun 26, 2009. 12:07 PM
A lego safe! Not practical, but a neat concept!
<smashes on ground and runs away>
Bartboy in reply to ArbitrorJun 26, 2009. 1:25 PM
Haha... the knex version can't be smashed!
Arbitror in reply to BartboyJun 26, 2009. 1:35 PM
But it can be melted, crushed, run over by a car, or eaten by knex haters.
ItsTheHobbs in reply to ArbitrorJun 26, 2009. 4:59 PM
Mmm..... crunchy. I like the little green pieces the best.....
Bartboy in reply to ItsTheHobbsJun 26, 2009. 6:47 PM
But the long black ones give you a real workout.... My favourite are the big yellow gears...
