Oscillating part for Harbor Freight heater

thingiverse

I have an old Harbor Freight space heater (Chicago Electric model 94777) that stopped oscillating, it turned out the plastic piece that connects the motor to rest of the mechanism was broken. After several attempts at gluing it back together only to have it break again, I found "Fan Oscillating Part" by The3dprinter. It was close to what I needed, but didn't quite fit. I'm terrible at TinkerCAD, so this isn't exactly a remix, I redesigned it from scratch in OpenSCAD and made it parametric. The defaults are based on the actual measurements of the broken piece I removed from the heater. I used the "remix" feature here to give credit since it was The3dprinter's part that inspired me to make this. Printed with an Ender 3 with eSun PLA+ at 230C, 50% cooling fan and 100% infill. You can probably get away with using any other filament and settings you would normally use for part that needs to stand up to a (very) little bit of stress.
