The wheel mount on our head and neck massager broke soon after arrival. This is a crude, yet functional, replacement.

It also gave me an excuse to try out the BOSL2 OpenSCAD library.

It could use some refinement, and the top wheel should be offset to make it easier to screw onto the motor, but it works fine as is.

I printed it in PETG using a “structural” preset and 25% infill.
