DIY universal controller pocket gamepad.
This is a open source wired controller/gamepad designed to be ultra portable.
It uses a RP2040-Zero MCU soldered onto a custom PCB (see files).
For firmware it uses GP2040-CE which can be downloaded from here:
https://github.com/MegaBitmap/GP2040-CE/releases
3MF Print files ready to be sliced can be downloaded from here:

If you have good first layer adhesion, disable brim.
~0.13mm layer height
Z seam alignment -> random
The faceplate must be printed facing up with generate support enabled.
The shoulder buttons need generate support enabled.
The D-pad is split into two pieces to allow it to print without support.
Use a dab of glue to attach the "D-pad-pin" with the pointy side facing out towards the PCB.
The "D-pad-pin" prevents left and right or up and down from being pressed at the same time.
After printing the faceplate and shoulder buttons, thoroughly remove all support material.
