Flexi Snake — print-in-place articulated fidget that coils
A print-in-place snake that prints in one piece, no supports, and coils into a full spiral in your hand. 16 necked vertebrae on captive ball-and-stalk joints, each folding 50-70 degrees, plus a carved head with eyes and scale rings. Fully parametric: dial the number of segments and their length right in the .scad.

Infinity Cube — Animal Fidget (folding magic cube, 48 engraved animals, two-colour)
A folding infinity cube (magic cube) fidget toy: eight cubelets linked so you can fold it end over end forever. Every one of the 48 faces carries a different animal silhouette. Prints fully assembled — the links are captured by the cube geometry, not glued — and the animals come as a separate inlay STL so you can print them in a contrast colour. Confirmed printed and everting on a real machine.

Oldham Coupling Fidget — Offset-Shaft Constant-Velocity Demo Toy
A desk fidget that demos the Oldham coupling: spin the bottom knob and the top knob tracks it 1:1 even though the two shafts are parallel but laterally offset. A floating middle disc carries the rotation while its centre orbits a little circle. Five printed parts (4 unique designs), all flat and supportless. Useless, just fun.

Trammel of Archimedes — Do-Nothing Machine Fidget
A classic 'do-nothing machine': a gloriously useless desk fidget. Crank the knob and the arm traces a perfect ellipse over an engraved groove — and that's it, it does nothing else, forever. Two dovetail sliders shuttle in perpendicular channels; a knobbed crank arm snaps onto both. 3 unique parts (print the slider twice), all flat, no supports. Honest heads-up: the motion is not glass-smooth — at the crossroad a slider can catch and need a tiny nudge.
