A spinner in four steps
- Pick the type. Bearing spinner, print-in-place spinner with no bearing, or a spinning ring.
- Choose the shape. Two to six arms in lobes, bars, ring, star, rounded or wing styles.
- Add weight. Pockets sized for bearings, hex nuts or coins, or leave the arms solid.
- Print and assemble. Press the bearing and weights in, or break the print-in-place hub free with a twist.
Settings that work
Press fit
If a bearing is loose, lower the bearing fit by 0.05 mm; if it will not go in, raise it. A drop of glue fixes a loose weight.
Print-in-place
Use the default 0.4 mm gap with a 0.4 mm nozzle, no supports and no brim touching the hub, then twist firmly to free it.
Long spins
Heavy weights far from the centre spin longest. Clean the bearing of grease for a free, quiet spin.
Fidget spinners FAQ
Which bearing do I need?
A 608 skateboard bearing (22 × 8 × 7 mm) is the classic. 688 and R188 make smaller spinners.
Can I make one without a bearing?
Yes. The print-in-place spinner has a hub trapped on a V-shaped track that spins once you break it free.
What coins fit the weight pockets?
US pennies, nickels and quarters and €1 and €2 coins are built in, or enter any round weight.
How do I find my ring size?
Pick your US ring size, or measure the inside of a ring that fits and enter the diameter.
