Spin-a-Roo: Ultimate 3D-Printed Disc with Marbles

Overview

Tired of your everyday play pucks?

Wish you could add a little pizzazz to your floor games?

Enter the Spin-a-Roo!

This marvelous 3D-printed spinner disc is here to turn your ground-play dreams into a whirlwind of fun.

Spin-a-Roo: Ultimate 3D-Printed Disc with Marbles

Equipped with an array of sleek marbles, the Spin-a-Roo glides across floors smoother than a penguin on an ice rink and spins in your hands like a ballerina on a sugar rush.

The trick behind the smooth glide is entirely mechanical: five loose marbles riding in slots between two printed half-discs act as a ring of tiny rollers, so the disc rides on rolling contact instead of sliding friction against the floor. It is the same principle behind a lazy susan bearing, just built out of printed plastic and hardware-store marbles instead of a sealed metal bearing, and it turns out to work remarkably well for something this simple to assemble.

The Spin-a-Roo is designed for maximum fun and minimal effort, perfect for indoor matches, epic trick shots, or just spinning away your boredom. Just give it a flick, and watch as it zooms and twirls, leaving your opponents dizzy with envy (and maybe a little motion sickness).

With Spin-a-Roo, you’ll be the floor disc champion, the master of marble spins, and the envy of every kid on the block. Whether you’re 8 or 80, this disc is your ticket to non-stop spinning action and laughter.

So rev up that wrist, and let the Spin-a-Roo mania begin!

Warning: May cause uncontrollable giggles and a newfound obsession with marble mechanics. Not responsible for any accidental breakdancing caused by the sheer joy of spinning.

Assembling

The assembling is easy and it does not require tools:

Print the two half discs in PLA or PETG, print the bumper in TPU, and take five 16 mm or 12 mm marbles/balls with diameters as close to each other as possible
