Hero Me Gen 4 OEM 4010 fan Duct

thingiverse

Since the original creator of the Hero Me Gen 4 didn't create a part cooling duct for the OEM 4010 fan, I decided to create one myself. I didn't want to use the old gen3 duct for the 4010 fan even though the creator says it's backward compatible. Try to print this part as I shown in the slicer screenshots - 0.16mm layer height - choose supports everywhere, 45deg, LINES support pattern (very important if you decide to use PETG) - put a support blocker near the duct end like in the screenshot - support density 20%, 1 wall line count, line distance 2mm, Z distance 0.12mm, X/Y distance 0.7mm - enable support interface (50% density) + roof & floor (93% density) - zig zag interface pattern - shell: 3 wall line count - 230deg hotend, 80deg bed - build plate adhesion brim 3mm - speed 45mm/s - infill pattern zigzag (very important if you decide to use PETG) - part cooling 50% This part finished in about 2.5-3 hours. I used painter's tape to make the PETG stick to the bed. Be careful to avoid any gaps between the strips of tape, since this annoying plastic doesn't want to stick even if it's the slightest line gap. Also, I used a pair of tweezers now and then because PETG has a tendency to be stringy and climb up the nozzle sides, and when it gets enough, it leaves blobs and strings over your print. Be careful so your tweezers don't get caught under the nozzle, because you'll have a great chance for a ruined print, or at least some skipped steps and shifted layers.
