StreamCompanion - your DIY button box

A simple, DIY button box with a cute little panda as your personal companion. It's an easy print, with slots for magnets (4x10 mm (2)) embedded in the print itself (1). Once printed, you can add any Cherry MX switches (and derivatives thereof with the same size) and solder them onto any board with any kind of keyboard firmware, and you're ready to go!

Depending on the firmware of choice, you can use it as a macro board for streaming, gaming, work or multitasking. I've gone with a Pi Pico and GP2040-CE  - a firmware with focus on gaming controllers. It also allows setting the keys up as generic keyboard inputs, including keys such as Mute, Sound Up, Sound Down, and Function keys which aren't normally on your keyboard (F1, F2, …, F11, F12, F13, …), but can be assigned in various apps and programs.

Notes:

(1) Double-check if there are pauses in the slicer. If not, and assuming you're printing 0.2 layers, there should be one at layer 139/140 for the box, and 14/15 for the lid. 

(2) Due to me running out of magnets, I had to embed one 2x10mm magnet. So long as the magnet is strong enough, this should work without any issues whatsoever.
