For games that use launch buttons instead of the traditional spring plunger (examples include Attack From Mars, Medieval Madness, Alien) the “LAUNCH BALL” graphic inside the button is screened onto a piece of plastic.

If you want to change that out for your own graphic just print this file in white (could also try translucent filament) and then add your graphic on top of it.

For a true ‘factory’ look you can vinyl cut graphics to add to the print. For those without access to a vinyl cutter you can just print a 1.88 inch / 47.9 mm circle and cut it out to place on the printed plate.

For best results if you use paper a little piece of tape on the back will keep it from rotating.
