I wanted my cheap AliExpress keyboard to look like a breadbin C64, so I photographed the keycaps on my own C64 and recreated the lettering as a font, including the 63 PETSCII graphics on the key fronts. The font is CC0: https://szabadkai.github.io/c64-keyboard-font/

The caps are SA profile. I printed them on a Form 4 in Tough 2000 resin, then sanded, inked and clear coated them. There are C64, plain and blank sets for ANSI boards from 60% to full size, as 3MF and STEP.
