Rubber-Powered Spinning Top

Wind, Push, Spin! 🌀 A rubber-band powered spinning top you can print, snap together, and launch — no batteries, no glue, no screws. Just wind it up, pull the cord, and let it rip. Quick to print, easy to assemble, and genuinely fun to play with. A great project to build with kids who'll love watching stored energy turn into spin. What you need: one thick, durable rubber band. 🔩 Use a thick, durable rubber band. Thin ones wear out or snap quickly — a sturdy, heavy-duty band lasts much longer and spins better. 🧵 PLA works, but PETG is recommended. PETG handles the repeated stress and tension far better, so your launcher and parts hold up over time. 🤚 Wind gently — don't over-wind! Cranking it too far will snap the rubber band. A few smooth turns is all you need to get a great spin.
