Impeller and Semi-axial impeller fans - 115mm diameter
thingiverse
Testing different designs for my bathroom exhaust fan. Definitely overkill but I'm having a great time and these 1mm blades print very well with zero thin-wall infill. fan is oriented with large side inside air duct and small end towards air intake (this is a ceiling exhaust system so the large end is the "top" inside the ceiling.) designed using fusion 360. 115mm diameter, 5mm hole for shaft
