Mega Zero Fan Duct (TCC)

Slightly more refined part cooling fan duct for the Anycubic Mega Zero.

**Edit**
Version 3 included which fixes some of the comments from users. Right hand side now slimmer to be in line with vertical piece attached to fan. Support steps added to top section under fan mount to allow support free printing. Ducts opened up on bottom face to direct air toward part rather than nozzle.

Based on user pal_lab's ground work combining the Anycubic duct with AustinAnywhere's Ender 3 duct.

Completely rebuild in Solidworks from the STEP file and optimised (mostly) for a support free print.

PETG/ABS/ASA recommended for the material.
Should print pretty well with no supports at 0.2mm layer height.
Best printed with a 0.4mm nozzle

Should be a straight drop in replacement for the stock part cooling fan. Just remove the bottom two screws on the fan and put this new one in place.
