Solidoodle Pico Hot-End Cooling Fan Duct (with mk5 mount)

This is a multipurpose fan duct for use with a Pico hot-end and Lawsy's mk5 extruder (jigsaw replacement).

I designed it to provide about 66% cooling to the hot-end, and 33% cooling to the extruded filament.

I haven't given it a try yet (need wiring connectors, etc) but the 40mm fan that comes with the Pico fits in nicely, and the duct mounts nicely to Lawsy's mk5 extruder.
