A simple and easy to print cat track for your cat. It fits standard 40mm ping pong balls (1mm clearance).
Balls bought from amazon here.

Add a ball (or two) to the tracks using the top hole, and then just wait. Some cats go crazy on these tracks, some don't care at all.
The balls can only be added and removed using the top hole.

I uploaded a few variants with different amount of cat icons (from zero to ten). You can spot the icon on some of the photos.
 

Print instructions:

I suggest you print the test piece first (preferably using a brim) to make sure the tolerances are good for your ball, and that the inner overhangs are not causing too much of an issue. If the fit is too tight, you can scale up the model by 1-2%.

0.20mm layer height, 15% infill, PLA, no support needed. Printed with brim, but probably not needed (leftover I forgot to remove from when I was printing the test part).
Post printing, I had to do some minor cleanup of dripping overhangs using a file, otherwise the ball did not run smoothly.
