{"product_id":"3d-printed-propeller-launcher-flying-rotor-with-pull-rack-6-colours","title":"3D Printed Propeller Launcher – Flying Rotor with Pull Rack, 6 Colours","description":"\u003cp\u003eThe propeller launcher is made of four printed parts: a grip with a spiral shaft and textured handle, a hub, a rotor coiled from three rings, and a T-handled toothed rack. Slide the rack horizontally into the hub and pull it with your other hand — the shaft spins the rotor up to full speed and releases it straight up. It climbs several metres, then autorotates back down exactly the way a maple seed falls.\u003c\/p\u003e\n\u003cp\u003eIt runs on pure mechanics: no batteries, no electronics, no springs, nothing to discharge or wear out. Everything is printed from PLA to order in Poland and hand-finished after it leaves the print bed.\u003c\/p\u003e\n\u003cp\u003eSix silk filament colours are available: red-yellow-green, blue-green-violet, red-gold, gold, black and white. The shades shift into one another with the light, and at full speed the rotor blurs into a single ring of colour.\u003c\/p\u003e\n\u003cp\u003eModel design: NUKDDD (MakerWorld). Printed and sold under the designer’s purchased commercial licence.\u003c\/p\u003e\n\u003cp\u003eOverall size: approx. 19 × 18 × 8 cm. Launch in open space and never aim the rotor at people or animals. Not suitable for children under 14 years.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eRack drive, not a spring — slide the toothed rack into the hub, pull it with your other hand and the rotor spins up on the spiral shaft, then leaps straight into the air; it autorotates back down like a maple seed, ready for the next launch\u003c\/li\u003e\n\u003cli\u003eA rotor of three rings instead of flat blades — a ribbon coiled into three loops catches air along its whole length, and at full speed it blurs into a single ring of colour\u003c\/li\u003e\n\u003cli\u003eFour printed parts: grip with a textured handle and spiral shaft, hub, rotor and a T-handled rack — assembled in seconds, with no glue, screws or batteries\u003c\/li\u003e\n\u003cli\u003eSix silk PLA colours — red-yellow-green, blue-green-violet, red-gold, gold, black and white; printed to order in Poland.
