Fidget Octagon

A fidget toy that keeps your hands busy at your desk. It sits flat as an eight-sided plate, and every way you move the stem gives it a different look — twist it and the 23 rings sweep around into a pinwheel, push and pull it side to side, or lift it and they step down into a pyramid. 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

23 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.

Twist It Into A Pinwheel
Leave it flat on the desk and twist the stem: the 23 rings sweep around into a pinwheel, every ring turning until its corners meet the ring outside it. Push and pull the stem from side to side and the rings shift off-center for a whole different set of visuals.

Lift It Into A Pyramid
Raise it by the stem and the 23 rings step down into an eight-sided pyramid. 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.

The One The Set Was Tuned On
This is the shape the whole set was tuned against: every ring turns and the stack stays together through a full twist. The gap widens from about 0.8 mm at the stem to about 1.4 mm at the rim, so the outer rings keep turning freely instead of binding up.

Slice It Right

These are the settings the octagon in the photos was printed with, on a Creality Hi 2 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: 3 h 22 m and 101.06 g for the whole plate.

It prints flat, just as it rests, 162.7 mm square and 39.0 mm tall with the stem, with no supports and no brim. It needs a 180 mm bed.
