Automatic Cat Feeder Replacement Rotating Arm

I got an Automatic Cat Feeder, it was from a brand called POOEKEN but not sure if these are generic or not however after a few months the rotating arm that moved the cat biscuits into feeder started breaking apart, strange as it was a flexible rubber and that type of material is usually pretty durable. Lots of bad reviews so clearly a common issue.

It ended up looking like the picture I've uploaded and didnt really dispense much food so I designed a replacement. The original had a little glue holding it in place and in my original testing it does need to be fairly well held in place else it can pop off.

Theres two different versions, one for TPU, which is the one I've been using/testing for the past few months without any issues and also one for PLA/PETG, which I havent tested personally, it will fit but maybe hard to get off again as it needs to be a tight fit to stop it coming off. I can only recommend the TPU version as its the only one I've tested.
