OpenSCAD Keycap Modeller
A very old project from 2018. Despite the sub-optimal and difficult to read code, I think it works quite well.
The keycap design can be fully customized by changing variables found at the top of the script, including size (1u, 2u, 6u, etc), text displayed, stabiliser type, etc.
More modifications to the design, for example concave depth, can also be altered if you dig deep enough into the code. There is also code provided to enable ‘walls’ around the keycap to mitigate 'oozing’ from a dual nozzle 3d printer when printing the text.
