Ticking Turn Timer — wind-up escapement, no electronics, no metal parts
A real mechanical escapement you can print: wind the knob, let go, and a foliot bar rocks tick-tick-tick while an arrow creeps back over the dial — silence means the turn is over. All 7 parts print flat and supportless; the only non-printed items are two coins used as tuning weights. NOTE: this is a mechanism demonstrator / desk toy, NOT an accurate timer — see the description.

Wand Through the Wall — a Straight Wand Passes Through a Curved Slit
A dead-straight wand on a little turntable swings clean through two CURVED slits in a wall, twice per turn, without bending. The wand is skew to the axis, so it sweeps a hyperboloid; the wall cuts that in a hyperbola, and that is the slit. Four flat supportless parts, formula engraved on the base.

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.

Tank Shooter — chunky display tank, print-in-place tracks
A chunky stylised T-34-ish display tank: articulated print-in-place link tracks that wrap the road wheels, a rotating turret, and a cosmetic gun with a friction-seated dummy shell. No glue, no supports, no hardware, AMS multi-colour. A DISPLAY model — the tracks don't drive and the gun doesn't fire.

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.

Desk Gyroscope — two-axis gimbal flywheel (a toy, not a tool)
A heavy-rim flywheel spinning in a two-axis gimbal on a pedestal — pull the string and the spin axis holds its direction while you tilt the base. A desk toy and physics demonstrator, nothing more.
