If you are looking to build a macropad with 9 mechanical switches and a raspberry pi pico inside this is the case you need. The design is a remix of VOID9 Macropad (based on the pro micro) and the Pico Armour case.
I’ve printed it myself and it fits perfectly, details for this build, instructions on how to set up the Pi Pico and the code itself are available from my blog: http://blog.4dcu.be/diy/2021/04/05/Macropad.html
More recently I’ve also programmed it as a MIDI device, if that is something you want to play with check out this post
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!
