Summary

None of the designs for wiper linkage bushings worked for my application, so I made my own easy print version for thrid gen Subaru Forester, and I assume outback and Impreza to. The dealer wanted 500 Eur for the whole assembly so well worth a weekend of trail and error.

My design is for TPU, you will not be able to squeeze theese on if printed in PLA, but PETG might work.

4 perimerters, 4 topp bottom and 25 infill meventually hit the sweet spot where the bushing locks over the wiper ball firmly and sits solid in the wiper linkage arm. Be prepared to struggle to get theese on, a hot air gun might be necesary.
