BMW Z4 E85 Cupholder Fix (internal)

thingiverse

My driver (left) cupholder suffered the expected break, but didn't break the arm like most. For me the internal sliding ratchet piece broke. I modeled up a replacement and it fit and slid easily first go. If I reprinted it I would probably make it a little wider as it has a couple degrees of freeplay. Not sure if that's just because mine is worn though. Because of the tiny nature and thin walls of the part I had to use my SLA printer to get it right. I did not fully cure the part in hopes of keeping it from becoming too brittle. I haven't used it too much yet so I'm not sure how long it lasts, but it at least works properly now.
