HyperCube Evolution Height Adjustable Fan Duct

This is a remix of the fan duct for the HyperCube Evolution. The original fan duct blew too much air against the hot end block so I wanted it to be height adjustable.

This fan duct distinguishes from the original in:
- slotted lugs so that the fan can be height adjusted according to the hot end clone height
- clipping of the sharp edge at the fan outlet to allow even further lowering of the duct.

I used PETG from ColorFabb to print the duct.

This duct works very well with the modular fan/e3d mount: https://www.thingiverse.com/thing:2777161
