3D Printable Tennis Ball Bike Suspension Project

Tired of a harsh ride? Welcome to the "NeoBall Rocker 3B Tripod" – a quirky, functional, and completely 3D-printable bike suspension project! This isn't just another bracket; it's a clever rocker mechanism that uses a few humble tennis ball as its core spring and damper unit. Squeeze the balls into the tripods,  and enjoy a noticeably smoother roll over bumps.

What makes it special?

Tennis Ball Spring: Provides a surprisingly effective and progressive cushion. Balls are cheap, easy to replace, and you can use old ones! Clubs often sell used ones in big bunches for less on ebay.

"Tripod" Design: The three-legged structure ensures stable, multi-directional support and looks fantastic.

Print-In-Place Simplicity: No screws, no glue – just print it as one ready-to-use piece (though a little post-print cleanup might help).

Print it in your favorite color to match your bike's style!

This is a perfect weekend project for tinkerers and casual cyclists. It’s a fantastic conversation starter and a brilliant introduction to functional 3D printing. I'd be thrilled to see your printed and installed creations – please share your makes and photos!

Assembly

This model is designed as a print-in-place part! It should come off your print bed ready to use. No tools or extra hardware are required for the rocker itself. No glue needed, just press in the balls.
