E3D V6 Mount for GeeeTech Prusa i3 Pro X

Because i did not find any mount for an E3D V6 (direct drive) for my GeeeTech Prusa i3 Pro X, i designed my own one.

Design goals:
- Mount should fit on the existing X carriage.
- As many old parts as possible should be reused.
- The loss in Z height should be as small as possible
- The outer shape of Part i3B1-30 should be kept to be able to mount existing stuff.
- As KISS as possible

Notes:
- a fan mount is available here: https://www.thingiverse.com/thing:2763717
