Challenge your cat (or small dog) with this print! Insert some treats and watch your pet rolling the tumbler around to get to the treats!

Standard PLA settings are perfect for printing. For assembly cut 9 Strands of filament to 9.5 cm and hinge the parts, as shown in the picture, together. Make sure the parts with the opening are exactly opposite to each other!

I have provided different difficulty levels. Choose a end cap and insert, you do not need to print them all. You can change the difficulty later on.
