Subaru Wiper Arm Bushing

Made this for my 1998 Subaru Forester, for the connection between the linkage and the arm on the wiper motor. Subaru doesn't sell this bushing as a separate part. Not sure what other models this will fit but it's designed around a 14mm diameter ball, and a 2.5mm thick arm with an 18mm hole. Design is parametric if you need to tweak that.

To install snap the bushing onto the ball first and then push the arm onto the bushing.

Minimal testing so far.
