40mm Fan Booster for Noctua

thingiverse

I changed my extruder fan to a Noctua 40mm and wanted to use a pressure booster. The Noctua has a smaller core than most fans so I designed a booster to have the proper core size to match for better air flow, I also included a part with a 10mm core to make it easy to create a custom part by just adding a paraboloid of the desired size.
