I made this button box for the PC game Elite Dangerous but this will work for any game that allows you to map joystick buttons.
It is fitted with the original 15 button Elgato Stream Deck (untested with Mk.2) and 16mm LED momentary switches, 16mm LED toggles, 6mm rotary encoders, and a 12mm safety toggle switch. You can customize the top plate mounting holes, positions and raised text to your liking with the included .step file. If you choose not to add text you can easily just use a label maker to label the switches.
I recommend using at least 5 walls and 30% infill or a strong filament such as PETG for the “Clamp Body” everything else can be PLA.
I've made versions using both the Leo Bodnar BBI-32 board and the Derek Speare Designs DSD32, both work great if you don't want to build your own button matrix, Links below with parts used.
There are two 16mm holes on the back of the box meant for these USB pass though mounts from Adafruit to power the button board and the Stream Deck USB-C to USB-A Panel Mount
Momentary Push Buttons (Self Reset, 16mm, 5v)
