Tough little storage box from muddymaker on Thingiverse:

UPDATE 27th February 2022- You can now print the little brother of this box here; https://www.thingiverse.com/thing:5265054
UPDATE 25th February 2022- I’ve added the step file for the entire box, dividers etc for anyone that wants to modify or customise the box to suit their own needs. I look forward to seeing what people come up with, good luck.
UPDATE 21st February 2022- Added a lid with holes plus a handle, you’ll need two M3x10mm fasteners.
If you have already printed the lid without the holes you can drill the holes. Hole size will be 3mm and centre to centre measurement is 60mm.
“UPDATE 13th February 2022- Added a seal for you folks that would like to print their own out of TPU. Recommended settings: 0% Infill, 2 perimeters and 2 top and 2 bottom layers.
Flat part of the seal is to face the lid.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
