Description

The "Infinity Scraps" Cat Toy (Ball-in-Ball Design)

Turn your 3D printing waste into a secure, rattle-and-roll toy for your cat! This model uses a clever dual-pause system that lets you upcycle filament scraps and permanently lock them inside a protective, durable lattice shell.

⚠️ The "Safety First" Difference

We’ve all seen standard "scraps-in-a-cage" style toys or loose DIY ideas where cats can accidentally pull out individual purge lines or small bits of plastic. If a cat swallows sharp filament scraps, it can lead to serious, life-threatening digestive emergencies. This design eliminates that risk entirely. Because the inner ball is physically "printed into" the large lattice shell, it is impossible for the cat to access the scraps inside. You get the fun of a rattling, colorful toy without any of the danger.

🛠️ How It Works: The Dual-Pause Process

First Pause (The Inner Ball): The printer will pause while forming the small inner ball. This is your chance to fill it with your filament "poop," purge lines, and scraps. Once filled, resume the print to seal the scraps inside the small ball.
Second Pause (The Big Ball): The printer will pause when the large outer ball is partially finished. At this point, simply place your finished small ball inside the large one.
The Result: When you resume, the printer completes the top of the large lattice ball, permanently trapping the colorful, scrap-filled ball inside!

🐱 Why You’ll Love It

100% Secure: No loose pieces, no choking hazards, and no way for your cat to reach the inner scraps.
Eco-Friendly: A perfect, functional use for all that "poop" and scrap material that usually ends up in the trash.
Built-in Rattle: The trapped scraps create a natural, engaging sound as the toy rolls across the floor.

🖨️ Printing Tips

Watch Your Slicer: Ensure your two pause heights are set correctly. The first is to fill the inner ball, and the second is for the final assembly.
Material: PLA works great for a crisp, clean finish.

@TyphoidJonesy

Hey there! This looks like a fun print, but I’m hesitant to try it based on AI photos- could you possibly provide real photos of your print so I can see the finished product? thank you :)

Really cool design. Easy print, pauses are setup exactly where they need to be. Incredibly smart idea with double ball system keeping any stray pieces from the scraps away from your cat. Keep up the good work. From one designer to another, I’m impressed.

I am giving 5 stars on the model itself. it printed great, the supports came off with some ease, and the pause worked as advertised. As far as a cat toy, its still up in the air if my cats will play with it. my cats typically chase the rattling balls, but this one might be to big. They seem to be unsure and slightly afraid of it. I might consider shrinking its size and be less intimidating.

@gimkid

if by safe you mean choking hazard that can break apart contained within a ball with holes and weak layer lines then yes safe

It was easy to print and looks very cool. It fell from the table and broke in two. I will reprint with increased wall strength to see if that helps!

what if the cat breaks it and the things go flying
