Fidget Triangle

A fidget toy that keeps your hands busy at your desk. It sits flat as a three-sided plate, and every way you move the stem gives it a different look — twist it and each ring turns until its points meet its neighbor's, push and pull it side to side, or lift it and the 13 rings 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

13 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 And Slide
Leave it flat on the desk and twist the stem: each ring turns until its points meet the ring outside it, and the whole plate shifts into mesmerizing designs. 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 13 rings step down into a pyramid. Three sides is few enough that the lifted stack reads as three flat faces meeting at the stem rather than a cone. Lower it back to the desk and it makes a satisfying sound as the rings come back down.

Prints In Place
All 13 rings and the stem come off the plate already captured inside each other — nothing to glue or snap together. Every ring sits the same distance from the next at every height, so each one turns freely instead of binding up.

Slice It Right

These are the settings the triangle 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: 1 h 33 m and 45.79 g for the whole plate, the quickest print in the shape set.

It prints flat, just as it rests, 155.0 x 134.2 mm and 39.0 mm tall with the stem, with no supports and no brim.
