Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4471281.

Due to a motor bearing failure in my mothers Oreck vacuum cleaner totally melting the plastic around the screw holes, I modelled and printed one of these replacements.

Printed in ABS 100% infill with supports everywhere and brim (Cura)

I've added standoff support legs with wide bases underneath to help with bed adhesion after a failed attempt. these are easily removed after printing.

A no standoff version is included if you prefer.

BTW the nut holding the fan is clockwise to unscrew not the normal anticlockwise.
