Reducer for Auto Fish Feeder

This ring fits snuggly over one of the more common automatic fish feeders to give you more control over the size of the opening for food delivery. This is particularly helpful for small pellet foods. This ring has openings from 1.5mm to 5.5mm in 0.5mm steps. The feeder's slider door, for adjusting the amount of food dispensed, should be opened all the way, and then this ring will slide over the end of the unit and fit snuggly over the opening. You can rotate the ring by grasping the plastic food reservoir and the ring and turning, or removing the ring and putting it back on with the opening size you desire aligned with he opening of the food reservoir.

My feeder is made by Lukovee but there seems to be many names for essentially the same feeder, or feeders using a similarly sized food reservoir. JuzPetz, Aquarium Co-Op, Qpets, petacc, Petbank, FishNosh, etc.

I used PETG because it is more flexible and its smooth texture slides easily against the fish feeder's plastic reservoir. PLA and other types may work as well.

I have included Fusion360 and .step files so you can do your own customizations.
