Part Cooling Fan Mount for E3D Quick-Fit Plate

This is a simple adapter for a 50mm (type 5015) radial part cooler fan.

The fan is lined up with the nozzle in the same way as the Anet A8, so most fan ducts made for that should be compatible. I'm using [Spriya](https://www.thingiverse.com/thing:2133328).

BOM:

* 5015 type radial fan
* fan duct to direct the air flow onto the print
* 4x M3 screws (length of about 20mm should work)
* 4x M3 nuts
