Inspired on https://www.prusaprinters.org/prints/43543-replacement-keyboard-feet/files I created replacement feet for my Labtec Ultra Flat Keyboard.
The OpenSCAD file is included for adaption to other keyboards.
On one image two printed parts and the last original feet are shown.
Printed on a Prusa MK3S.
I used PETG, making the part more flexible (and less chance of breaking. 0,4mm nozzle and 0.1mm layer height (the latter just because it looks somewhat better).
