So finally, here you can find all of the keycap models I printed/designed.
It's all WIP, so your results may vary.
Feel free to modifiy or extend the repo!
The work is based on the models of kekstee ( https://github.com/kekstee/3dprint ) The emerald is from here: http://www.thingiverse.com/thing:28377 The music symbols are also not mine, I do not remember where they're from, though (it's been a while)
