Kerdom 9070 head rest riser

Kerdom refused to provide taller headrests with their products so I had to make my own. Too bad.

Functional part, ugly af but serves its purpose. Easy installation and sturdy (given print config below). 

I'm 1'78m (5'10'' for those non-metric weirdos) and I keep the integrated heigth adjustment bar almost at the lowest position, so it will be great for people up to 1'85m. 

Any possible feedback/improvements will be greatly appreciated for next version.

Will probably work for other Kerdom chairs with the same headrest interface.

v2 ToDo:

1. Remove sharp corners
2. Allow head rest to sit completely vertical
3. Improve visual appeal (S shape) without reducing printability
