Filament Spool DIY Cat Dog Toy Treat Puzzle

Give your empty 3D-printing cardboard spool (or any similar spool) a second life as an interactive cat toy. This upcycle project adds sound, movement, and treat-puzzle play with a few quick 3D-printed parts—perfect for your own cats or for donating to a shelter.

• Compatibility: Designed around ~Ø200 mm spools and works great with the Bambu Lab reusable spool. If your spool is a different size, simply scale the printed parts to fit.
• Fast & simple: Prints quickly, no fancy settings required. Pop the parts in, load a few treats or a rattle pod/ball, and let your cat chase, bat, and roll.
• Eco-friendly fun: Reuses spools after you finish the filament—more play, less waste.

My cats love it—expect curious paws, rolling chases, and snack-time puzzles!

Safety: Supervise play, retire the toy if the cardboard gets soggy or damaged, and secure any tiny rattle parts if your cat is a heavy chewer.cat toy
