CR-10 Duct Fan Mod

A remix of a remix! I took the fillet remix Justinb81 did of Nexi-Tech's fan duct and altered the screw holes to give it more strength, as there was very little material around the holes which made the part extremely fragile. The screw holes now are better sized to the bolts while adding a lot more material around the circumference.

Printed and fitted! I used 2mm resolution supports for the holes only.
