Zyllion Shiatsu Back and Neck Massager Replacement Insert

I broke one of the plastic massage inserts in my Zyllion neck and back massager right along the motor shaft insert. I created a replacement part in Fusion 360. It's not an exact copy, but so far it has held up and works fine. It is slightly noisier than the original — I'm guessing because the round kneading areas aren't as smooth on my print as the original.

Printed with PLA. Might need something that can tolerate high temperatures better if you routinely use the heat setting on the massager. I used 80% concentric infill and 3-4 wall count with tree supports.
