Introduction: Lego USB Drive

Picture of Lego USB Drive

I created my own Lego USB Drive, I used the instructions that ianhampton did, here is a link to it. Here is what I did to make it.

Other tutorials used silicon to fill the inside, I used a 2 part epoxy. I just got the wrong thing but it works just as well and it is SOLID.

I'm going to be making a cap for it. Its becoming a pain because trying to line it up and fill it so it can go on.

Step 1: List of Parts & Tools

Parts List

- Cruzer mini USB Flash Drives
- 1 x 1 Tile
- 1 x 8 Plate
- 2 x 8 Plate
- 1 x 6 Brick
- 2 x 3 Brick
- 2 x 6 Brick

Tools (Not Shown)

- Exacto Knife
- Needle Nose Pliers
- Krazy Glue Pen
- Quick Set 2 part Epoxy
- Disposable cup or container to mix epoxy
- Rubber Surgical Gloves
- Rubbing Alcohol
- Rag

Step 2: Cutting the Bricks

Using the exacto knife I cut all the bricks. I also used the needle nose pliers to remove some of the bigger pieces and then cleaned up the rest with the knife.

Step 3: Pre Glue Prep

Other tutorials say thay had to use a steady hand while the glue set. I use some 1 x 1 round bricks and a 1 x 4 brick with a 6 x 12 plate to hold it while the glue set. I used the round 1 x 1 bricks to lessen the chances that the glue would get on the bricks. It only happened to one of them.

Step 4: Gluing the Bricks Together

Using the crazy glue pen put glue on each piece and put it on the plate. I used the circles under the plate to hold the parts better.

I know Crazy glue sets and hardens quickly, but I sell let it sit over night.

Step 5: Cutting the Opening for the USB Drive Connector

Most other tutorials show just cutting from the bottom, I was not about to do that. This was the hardest part to get it lined up correctly. I just carefully kept lining up the connector and using the knife to scribe a line to go by. Mine is not perfect but I think it came out good. I had to keep cutting and scraping to get the connector through the slot.

Step 6: Assembly

I took a 1 x 1 tile and glued it in side to act as a support to hold the USB drive at the correct height.


Next Insert the USB Drive in and position it and fill with epoxy, do not over fill. Sorry there are no pictures for this. I had to be quick with the epoxy. Do not over fill, and after you have enough epoxy put the 1 x 8 and 2 x 8 pieces on the back and CAREFULLY and I can not stress this enough, be careful, it will get very warm, as the epoxy sets. You will need to hold it for about 10 minutes. I built a jig out of other Lego's to hold it.

As the epoxy sets you might get some run off, this is where you might want to have some Rubbing Alcohol and a rag to wipe up excess run off that might seep out of the side.

Step 7: Completed Lego USB Drive

Here are the images of the Lego USB drive. not 100% perfect, but I'm happy with it.

how hard is it to cut the legos?

kurita_89 (author)2010-02-14

 Thanks for the idea! my dads had a usk full with maskintape... this really looks better!

Flecks (author)2009-06-17

I made one in a 2x4 block (: Also with a cap. Only difference i think, is that i closed it in the bottom, so it wouldn't be so big (:

tekjock (author)Flecks2009-06-17

Mine is closed on the bottom as well .. if you see the 2nd pic of step 7

Flecks (author)tekjock2010-02-08

I wish i could make the image stuff work....
Mine is only a 4x2 block, not even a 1/3 height block underneath, but still closed so i can build it into things.
And sorry i didn't see your reply before now (:

Jared Stipe (author)2009-12-08

Whoa! I can't believe how easy this was! And it looks cool too!

tekjock (author)Jared Stipe2009-12-08

Then post a pic ... lets see your work!!!! I hope my Instructable helped

tekjock (author)2008-05-12

Cool VId, Portable apps RULE. I have a 1 gig flash drive (Non-Lego) and I have a bunch of portable apps on there. You can learn more at That site and other sites. Very helpful. I use it on my work laptop all the time. and Portable KeepPass is one of my favs. I have it on my flash drive, Desktop and My phone.

Chromatica (author)tekjock2009-08-19

Agreed portable apps rules

Chromatica (author)Chromatica2009-08-19

Its on my ipod

TheLlehctim1 (author)2009-07-25

what kind of table did u use when you took the pictures

tekjock (author)TheLlehctim12009-07-25

don't recall ...but that is a piece of paper it is on

Fashim (author)2009-07-21

Wait arent there 2 of these posts?

tekjock (author)Fashim2009-07-21

Your not the first one to say that, but mine is different then the others, any way there many versions of many things on this site, this is just my interpretation

Fashim (author)tekjock2009-07-22


mechcem (author)2008-01-19

how do you open this kind

Fashim (author)mechcem2009-07-21

Sledge Hammer?

MXR789 (author)mechcem2009-04-21

i have that one 2. it is very easy to open. were the key-ring thing is just put one end of a knife or pen and kind of pry it off. it worked for me but remember while doing it make sure that the USB is slid out all the way to avoid damage.

N1CK4ND0 (author)mechcem2009-03-24

Cutting, I used to have the one. You need a very sharp knife and something to hold it with so you don't chop your arm off.

ProjectZro (author)mechcem2008-12-18

with a hammer lol, but seriously i think its held in by clips so try using a knife carefully

tekjock (author)ProjectZro2008-12-18

It is either Ultrasonic welding or it is heat sealed

Dante-sama (author)mechcem2008-07-23

On the bottom there is a small piece of cylindric metal, if you get a screwdriver and prize the two ends apart it opens =] I have one, love em! =)

mitchell931993 (author)mechcem2008-04-19

i used to have a memory stick like that-i had it in the computer and my ash tray fell off the top and it just snapped-u might wanna get the line screw driver and run it along the usb part to pry it open-but it might be an even better idea to run it along the white(to get a poking place and pry from there-because the white bit is sort of attached to the silicon chip but its easy to get off once the black plastic is off-it shouldnt be too hard cause there is like almost nothing holding it together-i think they just click it all together in the factory-sorry for the long explanation

tekjock (author)mechcem2008-01-20

Why would you want to, Thats a good one? I guess you just have to pry it open. OR ... I opened one of mine w/ an exacto knife, just scribe w/ pressure along the seem. BE careful, I sure I don't have to say that

That is a good one. Just go to Radio Shack and pick up a 1gb for under ten bucks then open it. P.S. I have that same flash drive.

hotchoc26 (author)2009-04-13

wow im gonna try this and show it to my friends!

hotchoc26 (author)hotchoc262009-04-13

i used a busbi stick that was a 1gb i didnt need much. i even opened it easily with my two hands!

N1CK4ND0 (author)2009-03-24

That thing is huge. I managed to fit mine in a 2x4 brick. Here is the pic:

Redrockers (author)2009-02-08

i filled the inside of mine with plasticne

J_SCAP (author)2009-01-19

im in the middle of making mine now i just have to find my flash drive >.>

tekjock (author)J_SCAP2009-01-20

Good luck, Post pics when done

Cloventt (author)2008-12-22

I just made this. Took me 1 hour and was really simple. I used instant setting super glue, so I didn't need to hold it for more than 10 seconds. It doesn't go into my old USB slots, but on my PCL board they fit just fine. I didn't use epoxy, I used layers of thin cardboard and they work great. Just so you know. Great article, kudos to whoever wrote it!

tekjock (author)Cloventt2008-12-23

Thank you, glad you found it useful

iwantacuracy (author)2007-07-22

if you used plastic glue would that kill the memory stick???

tekjock (author)iwantacuracy2007-07-23

no, I used a 2 part epoxy that HEATED up and it was fine ... you want to test its resistance to heat ... PUT IT IN THE DRYER. I put thru the dryer 3 times and still works

Arbitror (author)tekjock2008-11-21

My SD mini cruzer went through the wash, then the dryer. Its perfectly fine, the dryer removed all the water inside it!

iwantacuracy (author)tekjock2007-07-23

thanksand the memory stick still works

555mst555 (author)2008-09-03

how about making a jenga usb drive....i wanted to do that but i don't have the tools...:(

schmidtty (author)2008-04-04

check it out

schmidtty (author)2008-04-04

i did this exept i used a hot wheels car, and when you plug it in the inside of the car lights up red, and when you acces files on the drive, it flickers. its so cool, i got the idea of doing a lego one from u, but i couldn't find a big enough lego, cause i never did legos as a kid, all i had was knex. but i found a hot wheels car in there and i thought that would be even cooler, problem is its only a 128 mb drive cause i got it for free, and i didnt want to wreck my nice one

cool! (author)2008-01-20

Crap! you are good! I just dremmeled out a black 2 by 6 block and hot-glued it in... But yours looks really nice, and great idea! I have a method that works really well for filling with hot glue: Put plenty of glue on and then, before it dries, push it down on a sheet of newspaper. Use an exacto knife to cut off the extra glue, then color it with a sharpie (black, for me). It works well, but is not opaque.

tekjock (author)cool!2008-01-20

kewl ... post a pic here, I'd Like to see.

Shifrin (author)2008-01-02

This is great! Favorited!

tekjock (author)Shifrin2008-01-03

Thank you Sir!

Shifrin (author)tekjock2008-01-03

Hey, I speak the truth! you did an awesome job!

Shifrin (author)2008-01-02

Sorry for the double post but: To all the people who are mad at Tekjock for making this awesome instructable, compare the other instructable to this one... This one has: Better Instructions Better Pictures Its Easier! And Overall It Looks Better!

Arch Stanton (author)2007-12-13

Here's my lego usb drive i just put together .. I need to make a cap for it yet but...diggity !!

tekjock (author)Arch Stanton2007-12-13

It looks kewl .. is it a Lego or one of the other brands of building blocks

Arch Stanton (author)tekjock2007-12-13

It was regular old lego .. 2 pieces of flat 2x6 hollowed out and glued back to back. The usb circuit board fit in almost right inside after i filled the holes off ..shaved a bit off the circuit board and it fit together like it was meant to! ..I'm really happy with the way it turned out ..looks pretty sharp with the led lit up :} you can't really tell from the pictures but i used the metal collar and clear plastic led cover / tang from the original usb stick , covers up the rough edges makes the ends look nice and clean

tekjock (author)Arch Stanton2007-12-14

I like it, the metal collar fits nicely, and from the pic I could not see the Lego logo.
Good work

I made this silly lil' USB hub out of lego, it was a mini USB hub and a 1x1 brick fit perfectly between the 4 ports
