Introduction: DIY Lego USB Flashdrive

Are you a fan of Legos? Need a case for that small USB device, such as a flash drive or a USB dongle. Your at the right place. This project is somewhat simple to do, you just need some basic skills with a couple of tools! Lets get started!

Step 1: Gather Your Supplies

What you need:
Lego Brick-(I used a 2x6) Use what will work.
Lego Plate-(I used a 2x6) Use what will work.
USB Flash Drive
Dremel+ Drill Press/Router Bit or similar.
Hot Glue Gun-(what I used but use any other glue or epoxy that will hold well)
Vise-( I used to pieces of wood clamped together that were then clamped to the desk as a replacement)
Sandpaper-( I have these pen sandpaper type things that I think I got off a Website called Woodcraft, lot easier to work with)

2x2 Brick
2x2 Plate

Step 2: Prepare Your Brick

First, get your brick and clamp it with a vise or my method with the studs facing sideways and the small edge facing up. Now, place your Flash Drive on the bottom edge and trace around it. This is what you will cut first. Now undo your clamp and take your saw and cut along the lines your made. Then cut it all out using your Dremel or X-acto Knife. Once done sand around the edge to make sure it's clean and not rough. Now you will need to clamp your brick upside down and grab your Dremel began to cut out the inside. I used a 2x3 brick to be able to keep some of structure of the inside and well, my flash drive fit! View the pictures for detail. Make sure your drive will fit through the slot we cut and inside the brick. Also, make your flash drive to make sure it can still have to go all the way into a female USB plug. You are not finished with the brick.

Step 3: Prepare Your Plate

This is easier then the brick, don't worry! Grab your X-acto and then cut off however many studs you need to, I only had to cut off 4 out of 6. After your done, I suggest sanding off any bump you feel. You are now done with the plate.

Step 4: Gluing It Together.

I suggest gluing in your drive first. Ensure that your drive will and make sure it's facing the way you want it. (Make sure it won't be upside down when plugged into a USB port). Then, take your hot glue and fill in the gaps in the bricks structure ( i still had some parts of the brick left, depends with you) and then keep going a little extra so your Flash Drive has some to stick onto. Wait to dry some, with me 5-10 after contact seemed good but I kept pressing to make sure it's in there good. Now put some hit glue on the flash drive. Then align your plate to the bottom and press to ensure it will all stick together, completing the brick.

Step 5: Optional Step: Cap

Take a 2x2 square and cut out the inside. Then trace a slot for the flash drive head to go into. Cut it out. Then cut the insides out. Next take a 2x2 plate and cut all the studs off and then sand till there's no bumps. Now, use something like hobby glue or model glue and glue the plate to the brick. Your cap is finished.

Step 6: Finished Product!

Your USB device is now finished and better then ever! I hope you have enjoyed reading and please comment if you have any questions or comments. Also, if you could, vote for me in the Lego Contest and Glue Contest! Thanks!

that is a neat idea! Are they still stackable that would be really neat

CarterBond (author)SuziQG2016-02-21

Thanks! Yes, they can still stack on any brick and on themselves.

here's my take on Lego USB Stick. hope you like it. i will post another when I'm finished with the other one. the other's got a red light coming from a transparent red brick. :D

CarterBond (author)kiswinar2015-04-15

Very Cool! Looks great. Looking forward to the clear one!

maKACS made it! (author)2015-01-20

I made it out of 3 plate, so it's a full height 2x6 stud device. (Those days I haven't got smaller pendrive.) Whit wheels it's height fits exactly to my notebook's USB port, so the wheels are great support. :)

You gotta love Lego;) I made mine some years ago, similar technique and tools used as yours but I found a very small USB chip to work with that allowed me to use 2x2 pieces. The small rectangular hole was made with patience, a small drill and a scalpel-ish knife.

I haven't actually made it yet but it seems like something to get me back in my creative mood about myself thanks!

CarterBond (author)TheGreatLlama2014-07-16

great now not only that you can store presides memories you can receive extreme pain from the food while you are doing it

Ploopy (author)2014-07-08


This is so compact compared to others.

CarterBond (author)Ploopy2014-07-08

Thank you! With this flash drive, I could have made it be a square but I decided to make it 3 long because I thought it would be stronger.

dan14941 made it! (author)2014-07-07

Works well but I had to reconstruct the metal case of the end bit that's why its showing but it looks cool. I only got 1 cut in my finger be careful!

CarterBond (author)dan149412014-07-07

Looks good! Ya, gotta be careful!

Very nice idea

Very good. Might submit one of my Lego creations and give you a little competition. :) Bawahawaha

CarterBond (author)jjnn12014-07-04

Thanks, but noooooo! Just kidding, ha ha. Submit stuff!

Cobbled this one together last summer, works well but has been replaced with a much smaller (in size) drive. I like the hole I melted between the yellow pegs to show the read/write activity.

CarterBond (author)bigme2014-07-03

Very nice! My USB drive doesn't have a read/write LED. In mine I could drill two small holes for a string or lanyard like the plate you have in the back.

Cute idea!

Thank you!
