blade shaft coupler for Cuisinart Smart Stick CSB-75(AD) stick blender

thingiverse

This is the plastic coupler that attaches the motor to the shaft that drives the blade. Mine wore out and parts are not available for purchase. Hope it helps someone else too! I would guess that PETG or ABS would be better suited for this application, but I printed mine in PLA and it's holding up just fine. NOTE: The center hole is intentionally slightly undersized for a snug fit. What I would suggest is to gently heat the metal shaft coming from the motor (I used a soldering iron), then hammer the part home. The plastic will melt onto those ridges, which are not in the STL.
