I made these Cherry MX compatible keycaps in the style of the Sinclair Spectrum+ keys. The markings are recessed into the flat area, so light will shine through if you have a back-lit keyboard. I made 10 caps; 4 cursor keys, PrintScreen, ScrollLock, Pause, a blank one, one with a 4x10mm recess, and one with "zx+" on it. You can use the one with the recess to stick in 4x10mm printed labels with whatever marking you like.
To get a good fit on the Cherry MX keys, the slot size needs to be very accurate, so if your first layer is squashed you may have trouble getting the keys to fit. If you find this problem, using a raft may help.
I suggest printing this at 0.1mm layer height and >60% infill, with 5 base layers and 5 top layers. The high infill allows for good contrast against the backlight.
