Keycaps (Turkish) Logitech MX Mechanical Keyboard
IMPORTANT! These require a 0.2 mm nozzle (not layer height, but the physical 0.2 mm nozzle). They will not slice or print with a 0.4 mm nozzle or larger.
Some keycaps I've made from the blank template, mostly Turkish characters and volume buttons.
You'll need a 0.2 mm nozzle to print them. Alternatively you can remix/modify the letters to be thicker and then they'll print with other nozzles but that'll let less light to pass through the letters.
Use a material that lets the light through a bit. I've succeeded with pretty much every PLA+ from eSUN (including dark gray, green and orange pictured below) except for black. Black lets like zero light through.
I've included an SVG file for the font I've been importing into Autodesk Fusion if you'd like to add more letters with the same font.
