Rolling egg cat toy

An egg-shaped cat toy that rocks back and forth!Fill the top with treats, and enjoy. The print is three parts: the top, the bottom, and a screw to hold the two together. Add weights inside the screw to create the rocking motion, specifically designed to fit 4 Canadian Quarters, and can probably fit American ones as well. The screw can be a bit difficult so don't be afraid to push it into the top piece if it's having trouble aligning properly, it's relatively durable.
