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.

Squeeze Breeze — Trigger-Spun Fan Toy (no batteries, mechanical novelty)
A no-batteries mechanical novelty: squeeze the finger trigger and a multi-blade propeller on a flywheel spins up through a one-way ratchet, then coasts between squeezes. A satisfying hand-powered fidget that LOOKS like a hand fan. NOTE: it's a toy — the spinning blades move only a faint wisp of air, not a real cooling breeze. Multi-part, every part prints flat and supportless. Fully parametric OpenSCAD.
