Updated: original model has been removed and will be re-uploaded next time. Although the original fan isn't sufficient for filament cooling, we're still giving it a shot to enhance the fan duct with the same setup. The result of cooling is pretty decent / better than the original until replacing the more powerful 24V fan. Printing in PLA at a 0.20 mm layer height, with three or more shells. Support: Yes This thing was made using Rhinoceros 3D. Here's the 96-hour stress printing test result.
