Printed three of these, two in PETG (mini/regular) and one PLA regular size. They printed great but when you release the ball from the support, the bottom of the ball is a little wonky and the support itself leaves a mark depending on the filament you use. Will a cat care? No, it probably won't even care about this at all. I noticed this shape has some flex in the walls, and part of me thinks if you were to widen the walls, you could print the ball separately and then adding in it later.

my kitten likes her new toy ty for the design

printed the other day no issues, used a lighter and wood carver to remove the supports on the ball. kitten learning how to play with toys loves it

She cannot get enough

required a bit of cleanup where the ball prints but turned out great! whether or not your cat cares is another matter haha

aside from the fact that my cat doesn't want to play with it it's a very good model

a bit of a struggle to detach the track and the mini support holding the ball, left a bit of a mark not shown in the pic. kind of loud while ‘in use.’ a bit flimsy, I (accidentally) popped the ball out multiple times. cat loves it, however does not quite grasp the concept that you hit the ball, not the whole thing. had to attach Velcro to the bottom so it stays on the carpet lol

Great! My cats like this.

Amazing print! Works great if put some treats in for attention (or to make it harder for the cats to take, kind of like how the KONG works for dogs). My cats don't really care about it though in true cat behaviour, perhaps having the ball in a different colour would entice them more. The print looks very clean and elegant, I also had no issues with the supports. Thank you!

Absolutely lovely, and the cats are thrilled :)
