Hi-hat clutch

I was inspired by a local drummer KJ Sawka [https://www.youtube.com/watch?v=b98BJ36K1wo]
and wanted to mount my 10" splash cymbal above my hi-hat for a more compact kit. Instead of
buying more hardware, I learned CAD and designed this simple clutch in a few hours. This is
the third iteration - the other two broke when wailing on the cymbal. This one is quite strong.

Use an M4 nut and bolt to secure the clutch to the hi-hat shaft. If you don't have metric hardware
available, a #6 or #8 machine screw will work too. Hand-tightening the bolt should be sufficient,
but if the cymbal slips down the shaft, you can give the bolt a 1/4 turn with a wrench. My hi-hats
are Gibraltar with a 7mm diameter main-shaft. If your hi-hats have a significantly larger or smaller
shaft, then you may need to augment the design. I parameterized almost everything in the
CAD file.

=====
Update, after 6 months the screw part broke. I re-designed it to be a lot stronger and moved the nut/bolt to the bottom.
