Skadis desk mount/clamp

Basically, it's a desk mount for the skadis that uses a clamp. It's got slight wobble but not much I can do about it lolol

I remixed 2 designs and lazily put them together like I always do, the geometry is ugly but prints with no issues

Changes:

• I made the inside of the clamp smaller
• I made the holder part shorter slightly

These changes were mostly made just to get it to fit on my print bed lol
