Since I have 9 cats, this was bound to happen eventually…

I made a varied selection of cat toy balls, with different patterns and an internal sphere to cause some noise and irregular movement, so that your cats will be completely unable to resist playing with it :3

I made presliced versions of all the variants I currently have (I'll keep coming up with new ones constantly and adding them), and they come in two types:

• If you're lazy like me, and trust your print bed adhesion, there's a version without additional adhesion aids (I recommend using glue anyways)
• If you don't mind snipping a few strings and you fear the toy might get detached mid print, there's a version with adhesion aids (I recommend you start snipping the supports on the internal sphere first, and then move on to the ones on the outer sphere)

Now then, that's not all, I also uploaded all the ball design stl files, because the nice thing about this design, is that you can combine them directly in the slicer however you want, it's quite easy:

1. Start by dragging the stl of the sphere you want into the slicer, resize to whatever size y

1. ou need
2. Drag the next stl into the slicer, right click on it and press “center”
3. Resize the last stl you added to fit inside the first one (I usually like making it 25-50% smaller than the containing sphere, but you can play around with the sizes however you want)
4. Repeat the steps however many times you want
5. Select all the stl models you added, right click and press “merge”
6. Now you're ready to slice and print your custom toy!

I recommend using PLA for the best sounding cat ball, PETG for the bounciest ones.

I don't recommend the X pattern as it's a little fragile.

Enough reading, your cats are waiting, go!

Please be careful with toys for your pets, ensure that they are structurally solid before letting them play with it, or they might choke on a small piece breaking off, but other than that, have fun playing with your cats :3
