Momo Prototipo compact button hub

For my new Momo Prototipo classic wheel, it needed a spacer between my quickrelease and wheel. And then I might as well make it into a discreet buttonbox-hub.

2 files for now:

1: A 90mm diameter, 25mm high HUB with 2 buttons (12mm) and a rotary knob.

2: A 90mm diameter 25mm spacer, for those who just want a spacer.

I'm working on detachable horn caps.
