Arcade button parts
thingiverse
Two arcade button pieces for you to print in any color and material you want. You may need to clean the printed pieces a bit. They'll work better after some use. You'll still need a spring, the nut and the microswitch from a regular cheap button. I recommend using these for less used inputs (start/select) that you want to look cool.
