Fidget Circle

A fidget toy that keeps your hands busy at your desk. It sits flat as a smooth round disc, and every way you move the stem gives it a different look — twist it and the rings spin freely with nothing to catch on, push and pull it side to side, or lift it and the 38 rings drop into a smooth cone. The stem is textured for a tactile feel, and lowering it back to the desk makes a satisfying sound.

Every Move Gives It A New Look

38 nested rings hang from one textured stem, so whatever your fingers do, the rings follow — and it all comes off the plate as one print.

Spin It Freely
Leave it flat on the desk and twist the stem. The rings are round, so there is nothing to catch on and nothing to stop them; every ring turns all the way around and they shift against each other into mesmerizing designs. Push and pull the stem from side to side and the rings ripple off-center for a whole different set of visuals.

Lift It Into A Cone
Raise it by the stem and the 38 rings drop into a smooth cone. Lower it back to the desk and it makes a satisfying sound as the rings come back down. The stem is textured, so it has a tactile feel under your fingers.

Prints In Place
All 38 rings and the stem come off the plate already captured inside each other — nothing to glue or snap together. This is the densest of the shape set: 38 rings packed across 171 mm, and every one of them turns.

Slice It Right

These are the settings the circle in the photos was printed with, on a Creality Hi 1 with a 0.4 mm nozzle. The 3MF carries the full profile — open it in Creality Print or any slicer that reads 3MF projects and it is ready to go.

One color, no swaps. A single spool, no filament changes, no purge and no prime tower: 4 h 6 m and 131.58 g for the whole plate.

It prints flat, just as it rests, 170.5 mm across and 39.0 mm tall with the stem, with no supports and no brim.
