Cooling fan replacement, 17mm shaft

thingiverse

I created this using Fusion 360 to replace a broken cooling fan on a Delta disc sander. I expect it will fit many motors. I think the outside diameter was about 145mm The shaft size is 17MM. The shaft actually micked at 17.03, I made the part 17mm and it is a tight fit, i just tapped it on the shaft. I thought I might have to tap it for a set screw but I don't think it will be necessary with the tight fit.
