Hero Me Gen 4 OEM 4010 fan Duct

thingiverse

Since the creator of Hero Me Gen 4 overlooked the part cooling duct for the OEM 4010 fan, I decided to design one myself. I deliberately chose not to use the old gen3 duct for the 4010 fan despite the creator's claim that it is backward compatible. Try printing this part as shown in the slicer screenshots: - Use a layer height of 0.16mm. - Select supports everywhere at a 45-degree angle with a lines support pattern, which is crucial if you plan to use PETG. - Place a support blocker near the duct end just like in the screenshot. - Set the support density to 20%, one wall line count, two-millimeter line distance, 0.12-millimeter Z distance, and 0.7-millimeter X/Y distance. - Enable the support interface with 50% density plus roof and floor at 93% density using a zig-zag interface pattern. - Use three wall line counts for the shell. - Set the hotend to 230 degrees Celsius and the bed to 80 degrees Celsius. - Apply a build plate adhesion brim of 3 millimeters. - Print at a speed of 45 millimeters per second. - Choose an infill pattern of zigzag, which is essential if you plan to use PETG. - Set part cooling to 50%. This part took around 2.5 to 3 hours to finish. I utilized painter's tape to ensure the PETG adhered to the bed. Be cautious not to leave any gaps between the strips of tape because this pesky plastic refuses to stick even if there is a slight line gap. Additionally, I occasionally used tweezers due to PETG's tendency to become stringy and climb up the nozzle sides. When it accumulates enough, it leaves blobs and strings on your print. Be careful not to have your tweezers get caught under the nozzle because you'll likely end up with a ruined print or at least skipped steps and shifted layers.
