Saw one similar but it required a ton of support. so I fabbed up this one that requires no support at all. used the chain customizer and the artsy fish in tinkercard merged them with a simple handle to make a one piece print in place cat toy

BE WARNED you are quite literally trying to print nearly 50 separate parts simultaneously and worse 45 of them are have a TINY foot print on the platten. Have fun :-) took me a couple tries to get those first layers to stay put :-)

The hold down tabs for the handle just tear off with your fingers when its done.

My cat seems to enjoy it :-)

If you have a smaller bed say 200x200 it should be fine to resize it slightly to fit in the bed dimensions. in fact the one in the attached picture was resized to 200x200 to fit that particular machine.
