cat ring with bumps

My cat likes to bat around rings, but they go under the frig, couch, stove and under closets doors.
So I make one high to not fit under, but he didn't like it.
so I went to tinkercad and designed one with "ears".
This way it's light weight and small and he can't bat it under things.
It's take about an hour to print with 20% infill, I use a brim.
