OpenSCAD cat toy
Gotta give props to Brian Enigma on instructables for getting me started. After a ton of tweaking and 4 prints I have my cat toy with a ball inside. It has a small cylinder on the bottom that acts as a raft. It was hard to bust that off, but I am happy with the result.
Printed at 5%, no raft. Takes about an hour. That was with accelerated speeds too.
