A little toy that I realized for my loved cat, Nina.
It’s a simplified but larger version of similar mazes that you can find in the commerce.

The idea is to drop some croquettes in the middle of the plate and let the cat to find the best solution to grab them. My Nina had some difficulties at the beginning, but after a couple of days, she becomes smarter and found several shortcuts to get the prize!
I added a little video with Nina in action! (https://youtu.be/K9ANOgDozwQ).
In any case is a good system to feed slowly your cats and making them work to get what they want.
The 4 plates assembled measure 28,3 by 26,4 cm (11,1 by 10,4 inches) and you will need 90 sticks.
I made this in PLA, printed with a 0.5 mm nozzle and 0.4mm layer thickness, no supports needed. The filling was set at (only) 10% for the plates and 25% for the sticks.
I recommend at least 3 borders and 4 top layers.
NB: for speed reasons, I suggest to print the sticks in horizontal position
