This is my design of a replacement back for an original Nintendo gamepad, for use with a Raspberry Pi Zero V1.2, Raspberry Pi Zero V1.3 (camera), or Raspberry Pi Zero W V1.1 (wireless) running RetroPie. I've designed this for genuine NES-004 controllers, so it's probably incompatible with the modern 'retro' hardware from China. This isn't strictly a remix, but I like to credit those who came before me.

Print with support inside the recesses for the case screws, and depending on how well your printer handles bridging, inside the port openings. I recommend PLA with 0.4mm extrusion, 0.18mm layers, 2 perimeters, 25% infill. Taking the outermost perimeter slowly will reduce ringing artifacts on most printers, for cleaner port labels and mushberry.
