Cat Marble Toy Playpen

This is a playpen for 2cm marbles for cats. The shape is such that there are lots of interesting ways to bap the marble around, but it's setup so that the cat just can't get the marble out. Well, mine can't anyway. Yours might have better luck. Hopefully this will entertain your cats without causing dangerous marble spillage everywhere. Print does require supports (and lots of removing of supports). 10% infill seems fine. 2cm / 20mm marble recommended (too small and it will escape the bars). Feel free to edit and remix.
