Wanhao Duplicator 6 Fan Duct (Improved Magnum: "Supermagnum")

thingiverse

Update: Centrifugal Blower Supermagnum variant and adapter (Which will fit the axial if you're converting over but are willing to sacrifice some airflow) is available here: https://www.thingiverse.com/thing:2452863 An upgraded version of The Magnum. May contain nuts and/or be processed on machinery that handles peanuts as well as: 1. Significantly enlarged ports, easily doubling over the unreleased proto-Supermagnum and quadrupling The Magnum. 2. Ports are angled at a closer to 30-degree slope, making it easier to print. 3. A ring of slightly larger diameter maintains distance from the heater block. 4. Port length is elongated. 5. Ports are aimed slightly more downwards to direct airflow towards the object's surface. 6. Bridging assist feature angle changed to 45 degrees, requiring a bit more mess but offering more space for fans with smaller hubs. Doesn't contain: 1. Heavy sarcasm. 2. A brand-new design. 3. (As of publishing, this will be corrected) Photo of the actual printed one because the sun is rising outside and my brain is exhausted. 4. A logical sequence of photos due to the sun's position. Place your finger under a cool nozzle or in front of one of the ports; you can feel the airflow, even with the stock fan. A further update may be released with bridging assist for the ports; however, I recommend rotating layers so that the bridging layer does not align parallel to the port. A 15-degree offset should suffice. Consideration is being given to making an air induction variant of a direct cooling system to increase volume, but higher pressure might win out. A 40mm centrifugal version of the SuperMagnum will likely be released soon, with a possible redesign for efficient use of space. Alternatively, a simple adapter bracket that allows existing SuperMagnum and Magnum to interface with a centrifugal may come first. Remember to print the fan standoff; see The Magnum if you want to print this but don't know why it includes an additional part and need guidance. Warning: Using these ducts will lose about 1 inch/2-3cm of print area in the left corner (Perspective: You facing the printer) due to motor interference.
