Modified Coleman Mach 1472A1191 A/C Blower
thingiverse
This project was designed because Coleman Mach A/C units ship with cheap Chinese blowers whose plastic softens when in hot temperatures while the impeller is spinning causing the blower to eventually break and throw shrapnel plastic within the A/C unit's directional baffle. I upgraded the part to include two additional impellers that serve to aid in drawing air into the blower. I have yet to print this part, but the dimensions are correct (7.28" height, 6.29" diameter). Ensure it will fit in your unit before wasting plastic on an attempt!
