Introduction: Knex Leave Me Alone Box

Hello everyone! What I have here is a small project that I worked on for a few weeks: a leave me alone box! I've seen lots of these boxes around on the internet, so I decided to build one out of Knex. :-) It is purely mechanical and uses things like an arm, crank, and a more compact version of the motor switch system I invented in my skeeball machine

Note: If you use the mechanism anywhere else, please give me credit. 

Here's a video of the box in action:

Step 1: Time to Count! (Optional)

These are the pieces I used to build the leave me alone box. The box uses a lot of pieces, so if you don't have enough you could make it with blue/yellow rods instead of green/white rods. The pieces below are listed with their classic-colored names. Counting is so much fun!

Rods: 436

green- 263
white- 156
blue- 8
yellow- 7
red- 2


Connectors: 265

dark gray- 24
light gray- 9
red- 29
green- 7
yellow- 24
orange- 13
white- 51
blue- 14
purple- 94


Other: 57

blue spacer- 20
silver spacer- 11
tan clip- 11
black Y clip- 10
medium yellow gear- 1
small blue/brown gear- 1
newer-style battery-powered motor (green)*- 1
blue hinge- 1
black/green hinge- 1

Total: 758

*You must use this type of motor. Keep in mind that motors of different colors go different speeds.

Step 2: Bottom Panel

Let's start off with something simple. This is the bottom of the box where everything will attach.

Throughout this Instructable, make sure to pay attention to the numbered picture descriptions.

1- Build it!
2- The bottom of the bottom. See what I did there? ;-)

Step 3: Motor

Now you will attach the motor to the bottom and slide in the axle.

1- Build these.
2- Another view.
3- Attach the one with the yellow connector to the motor.
4- Attach the other side.
5- Connect the motor to the bottom.
6- Another view.
7- Get these things for the axle.
8- Slide it into the motor as shown.

Step 4: Motor Switch

Now that the motor is attached, it's time to build the motor's switch.

1- Get a yellow rod and put it in between the motor and casing.
2- Get a dark gray connector and connect it as shown.
3- Get another dark gray connector and connect it above where the motor's switch is.
4- Build this thing, which will strengthen the switch.
5- Another view.
6- Attach it to the motor section. The switch should now slide nicely in either direction if you move the yellow connector.
7- Another view.
8- Another view.

Step 5: Gear and Rods

Everybody likes gears! After the gear, you'll add it some random white rod things.

1- Build this.
2- Another view.
3- The gear section attaches to the bottom in two places.
4- Another view.
5- This will secure the gear in place.
6- Another view.
7- Attach it like so.
8- Get these.
9- Attach them to the blue connectors.

Step 6: Lever

This lever is what you will push to activate the machine. 

1- Build the lever.
2- Another view.
3- What?! Wrong lever, skip to the next picture...
4- Attach the lever. Make sure the white rods it attaches to are pushed all the way down.
5- Another view.
6- Another view.
7- Build these random things.
8- Attach them to the bottom.

Step 7: The Crank

If you're feeling cranky, then this step is for you. Also included is a section of wall for the box.

1- Build the crank.
2- Attach it to the yellow gear's axle.
3- Get these.
4- Connect them.
5- Build this square.
6- Slide it onto the white rods.
7- Build this.
8- Slide it onto the white rods.
9- Build a wall section.
10- Attach it to the rest of the model.
11- A view of the other side.

Step 8: The Arm

Now you will build the box's arm and the shutoff arm.

1- Build the shutoff arm.
2- Another view.
3- Connect it to the motor's switch. 
4- Another view.
5- Build the arm's axle.
6- Another view.
7- Another view.
8- Attach the axle to the rest of the model.
9- The shutoff arm should fit over the axle like so.
10- Another view.
11- Connect the white rod of the crank to the dark gray connector.
12- Build the arm.
13- Connect it to the axle.
14- Get these pieces.
15- Add them to the edge of the axle.

Step 9: The Box (Part 1)

Now that most of the mechanics are finished, it's time for the box!

1- Build this wall.
2- Another view.
3- Attach it to the rest.
4- Build another wall.
5- Attach it to the rest.
6- Build this. It's part of the top covering.
7- Another view.
8- Another view.
9- Build this section.
10- Combine the two sections.
11- Attach it to the top of the box. Notice how the arm is resting on the orange connectors.

Step 10: The Box (Part 2)

More box building, yay!

1- Build this.
2- Another view.
3- Attach it to the rest of the box.
4- Build another wall.
5- Another view.
6- Attach it to the rest.
7- Build this small thing.
8- Connect it to the box.
9- Build another small thing.
10- Attach it to the box.

Step 11: The Lid

You're almost done! You just have to build the lid and finish the box.

1- Build the lid.
2- Don't forget the hinge!
3- Add the lid to the box.
4- Connect the hinge.
5- Another view.
6- Build this section.
7- Attach it to the box.

Step 12: It Has Been Completed!

Congrats, you have finished! Your box will now want to be left alone. Just push the switch toward the lid and watch it turn itself off.

author
Shadowman39 (author)siamesederp2017-04-18

There's lots of them on eBay, most likely good deals.

author
siamesederp (author)Shadowman392017-05-19

yeah, I got a Screamin Serpent, Loopin Lightning, and a Doubbledare Duelling Coaster all for $40 plus an extra 470 pieces because the Screamin Serpent shipped late =)

author
Shadowman39 (author)siamesederp2017-05-21

Haha that's cool, do you like micro coasters more than SS?

author
siamesederp (author)Shadowman392017-05-22

I like them both because they both are so fun. I can't decide which I like better

author
Shadowman39 (author)siamesederp2017-05-23

Hehe, it's good to like building a variety of things.

dynamite_kid (author)2017-05-05

this looks really cool and i want to build it, but the only problem is that i dont have enough pieces

but its AWESOME!!!!!! i wish i had enough pieces to build this

author
Shadowman39 (author)dynamite_kid2017-05-06

Thanks! Is it the box itself that you don't have the pieces for?

author
dynamite_kid (author)Shadowman392017-05-09

yes

author
siamesederp (author)2017-04-02

Going to try to build it, not sure if I have 263 little black/green rods tho....

author
Shadowman39 (author)siamesederp2017-04-03

Most of the green rods are used in the box itself, so you could make most of the box out of different pieces if you wanted to, like this white rod lattice:

siamesederp (author)Shadowman392017-04-29

Ordered $40 worth of knex, half of it was for this, the other half for my new K'nex roller Coaster I am going to post the preview for in a minute or two ;)

author
Shadowman39 (author)siamesederp2017-04-30

Cool! I'll go look at the coaster.

author
siamesederp (author)Shadowman392017-05-04

oh yeah, I had even less whites than greens soooo.... I couldn't make the white lattice

random_builder (author)2016-12-31

AWESOME!!! I think that this is the best knex anything on instructables. It is very cool and the instructions are very good. I had to tweak it a little but it still works great.

author

Thanks man! I'm glad yours works well.

author
Jedi_man (author)2016-07-04

This was a very fun build! Very good instructions.

I've always wanted to make one of these boxes :)

author
Shadowman39 (author)Jedi_man2016-10-09

Thanks!

Proassault (author)2016-10-08

Nice job! I made it but I needed to make 1 or 2 modifications to make it work

author
Shadowman39 (author)Proassault2016-10-09

Thanks, I'm glad you got it working!

The Knex Inventor (author)2016-06-04

Looks like a fun little project. I will have to build it sometime.

author

Thanks!

GuppehsWorld made it! (author)2016-03-06

This is such an interesting build. It took me about 1 hour 15 minutes to make. I love all the complex mechanisms in that small of a place. :D

Just finished the "Leave Me Alone Box" last night. Fantastic build, fantastic design, and fantastic instructions. I had a few snags but nothing that couldn't be fixed with a little bit of tweaking. Loved it! Thank you Shadowman39 for the design and instructions!

Hey shadowman I hope its ok but I used a bit of your mechanism in a K'nex ball counter I made I just used the casing for the motor switch system but I changed all the other parts of the auto turn off I hope thats ok I credited you in it :)

author
Shadowman39 (author)NorthernF2016-06-27

That's ok, I saw your ball counter, nice job! And thanks for the credit.

author
SacredSpriter (author)2015-11-05

I'm just wondering, how did you put this into the skeeball,have it release the balls (hahahaha
) and be activated by a quarter?

author

This was used many times in skeeball, there were 6 of the motor switch modules: 4 for the counter and 2 for the startup/shutdown.

author
Linkin_J_Knex (author)2015-10-17

Hehe great idea! I have to remember to build this!

author

Thanks!

author
crestind (author)2015-08-26

Had to watch the video to understand what was happening. Double crank to reverse the rotation. Brilliant!!!

author
Shadowman39 (author)crestind2015-08-27

Thanks! :-)

SirDaftBunny (author)2015-07-05

This was a really cool project to build! I had a few difficulties though. The part that is supposed to turn it off worked a lot better when I wrapped a rubber band around it, adding more grip and size. One more thing, please highlight the importance of connecting certain gears! I forgot to and ended up having to basically dismantling half of it :P
