Ender 3 Part Cooling Fan Duct

thingiverse

This is a minor remix of the original. I added a bit material to the mount tabs, making them stronger, after the original broke during its first assembly. No problems since beefing up the mounts and several hot end disassembly's. The other changes are just cosmetic. After using this for a while, I like it a lot! It doesn't drag on parts or interfere with nozzle maintenance. It does cool well... within the limitations of a single 4010 fan (now running a 5015 with a different duct.) It is noticeably better than the factory ender duct and as good or better than a few others I have tried. Good job to the creator of the original part.
