This is a parametric model of an impeller found in a bathroom exhaust fan. Use OpenSCAD's customizer to configure this model.
Before printing the whole part, print a quick test part with the hubOnly
parameter enabled. Adjust the shaft diameter until you achieve a snug fit.
I used the 0.3mm DRAFT print settings (20% infill, 2 perimeters) with my Prusa i3 MK3 and Prusament PETG with the official filament profile.
The author marked this model as their own original creation.
