CR-X Hydra mount

Rough remix of hydra fan duct frame mount to fit on a CR-X. I printed the CR-10 one out before I realised the CR-X X-carriage plate is totally different. The horizontal top part of the plate that covers the rollers means you can't use the connecting front and back design from the original hydra mount, so I changed it to only mount on the front and to allow for the position of the X-carriage mounting bolts.

crx_hydra_no_lower_hooks.stl just screws on to the front of the plate at the same points as the stock mount and can be printed without supports.

crx_hydra.stl has added hooks that hold onto the bottom of the X-carriage, but needs supports under the hooks.

Both will take the part cooling fan holders from the original hydra fan duct and a 40x10+ inline hotend fan (or the Hydra Fan Duct Heat Creeper by iAM_B3nFPS https://www.thingiverse.com/thing:4155280).

centri4020mount.stl converts the 40x10+ hotend fan mount to take a 40x20 centrifugal fan.
