Update: 24/05/20 Uploaded Step file. Jan 2020: Check out my latest design - Hydra Fan Duct & Tool Change System. I think it's a big improvement over this Hero Me remix in several ways. Link: https://www.thingiverse.com/thing:4062242 Hero Me 4010 Dual Fan Duct with Improved Nozzle Visibility Note that this is only the 4010 dual fan duct, not the full collection of parts. This design is a remix of Mediaman's excellent Hero Me Fan Duct Design. Thanks to Mediaman for creating it. I've found it really improves prints, especially with larger nozzles. I had some trouble importing Tinkercad OBJ files (the countersinks walls around the part fan fixing holes are thin) so I created the design from scratch in Fusion 360. In this remix, I made several changes: 1. Raised the connecting cross bar for a clearer view of the nozzle. 2. Redesigned the duct outer shell to print without supports. 3. Tweaked the fixing and location boss for added robustness. 4. Revised part fan fixing counter sink holes to remove the thin wall issue. Printing: 1. Printed without supports, but you may want to add a single custom support at the center of the cross rail to help with bridging (see uploaded image). It prints fine without one, though. 2. All prototypes printed well without a raft, but consider using one if you don't have great bed adhesion. 3. Printed with Black PETG, 0.2mm resolution, 30% infill, and 3 perimeters. Sorry in advance if there's a similar remix I haven't found - I didn't check against all the other Hero Me accessories. My main goal was to increase nozzle visibility. Thanks again to Mediaman for their excellent design.
