This is a replacement for the fins of the EUGAD automatic pet feeder. These fins form compartments where the food collects. When the motor rotates them, the food is pushed out of the feeder.

The original fins are flexible, so it might be better to print this with something like TPU.

The model contains both the fin with the bottom corner cut out, so it fits exactly like the original fins. Even without the bottom corner cut out, the fins are able to push the food out. Depending on the angle of the food there is a small chance it might get jammed though. Note: the STL for the cut corner was rotated 180 degrees. For printing it's better (less supports needed) to rotate it back.

The side that slides into the hub is tapered so that it slides in easily and will stay seated properly.
