Replacment impeller for a blower fan. It broke and needed a new one so I designed and 3D printed another! It works great. Fan housing MODEL NO. CCL-AD-09-003 (120V 60Hz 1.5Amax. 180Wmax) Motor MODEL SCH1084S3A (120VAC 60Hz 0.54A)You might need to take a dremel and carve out the center hole a little. It needs to fit snug on the motor shaft. Fit impeller on motor shaft then put the clip pin back on. Wear safety glasses and be careful testing it. This was designed from scratch by the way. The impeller is slightly smaller to avoid possible contact with the housing wall. It really pushes some air. I used silver PLA from JustPLA and printed at 190C, 0.2mm height, 0.55mm nozzle, 70C bed.
