Got one of these automatic feeders for my cat: https://www.amazon.com/dp/B0BW3L59HR Unfortunately my cat is very bad and stuck her claw up the chute to try and pull food out, ripping out all the silicone flaps on the drive wheel (the 6-sided wheel underneath the 3-sided wheel in the food chamber).

Printed this in TPU. Fits easily and feeds again. $40 saved. No supports needed, print on flat side. 100% infill. If your cat is particularly skilled at removing these flaps, you can make the flaps thicker. I wouldn't recommend printing this in brittle plastics like PLA, as at best the machine could get clogged and break the motor in it and at worst your animal could get injured via getting their appendage stuck in the chute while it is rotating.
