This came from wanting to teach myself Fusion 360. I had a hard time trying to print keycaps for my keyboard a while back. I eventually realized my keyboard uses Outemu Keycaps, not Cherry MX. Outemu has a bracket that surrounds the "+" which most 3D Printed keycap designs won't fit. This one should be more universal than some of the other 3D-printed Keycaps.

I added the f3d file so you could customize the top.
