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.

Ship's-Wheel Earring — Free-Spinning, Print-in-Place
A miniature ship's-wheel (helm) charm whose wheel actually spins on its bail. Printed as ONE support-free job: the wheel comes off the bed already captive on a fixed axle between a foot and a top cap. Flat print, vertical axle, so every wheel-to-frame clearance is a clean horizontal gap — no supports, no teardrop bore. Symmetric — print twice for a pair.
