Seed stopper feeding bowl rim.
by Walt, published
This is a snap-on rim for a size 3 (4.75" diameter) parrot feeding bowl. The parrot may eat more of the rim than the seeds, but if it doesn't then no more scattered seeds. The rim diameter can be created in different sizes easily by lathing the attached profile in CAD. Just make sure to slice a thin section out so that it can be pulled open to snap around the bowl edge. (printed with supports for the inner groove)
