Front Fan for Ender 3.
thingiverse
No supports. It might require a bit of delicate drilling for the shaft to fit. I aint promising any engineering marvel, but this is the best fitting iteration I've had so far on my broken fan. // I dremeled out the old plastic fan being careful not to hit the copper on the stator, and pried it out. The original fan is fixed on the small center shaft and has a pressfit rotor.
