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.
