PXP-Gamepad DIY universal controller pocket gamepad. ALL DESIGN FILES CAN BE DOWNLOADED FROM HERE: https://github.com/MegaBitmap/PXP-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 3D Print Settings 3MF Print files ready to be sliced can be downloaded from here: https://github.com/MegaBitmap/PXP-Gamepad/tree/master/3D_Files/3MF_Mesh 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.
