Lenovo Thinkpad T15g keycap broke. Designed a replacement that works. Took some trials to understand scissor-switch mechanics.
PLA-Tough, 0.2 mm nozzle. Might redo in PETG, PETG-CF or ASA.
Update: uploaded the Fusion360 file. This was a difficult design and print, to be honest, but maybe it could help you with any other key.
