C64U - Rear Mount - 3 Button

Decided to make it myself. I used 6x6x8 Tactile Switches (from Amazon). Wiring (from Amazon). Check all the pictures. This should answer 90% of your questions. You need to be comfortable with 3d printing, wiring and soldering. The STL for the back plate needs to be printed vertical and with auto tree supports. These are connected to P4 on C64U motherboard (Right/Mid/Left/Ground). Wire at your own risk.
