String Spinner

🌈 String Spinner – 3 Designs | Handle Included A simple and fun 3D printable string spinner based on a classic spinning toy. The set includes 3 different spinner disc designs and a specially designed handle that makes the spinner more comfortable to use. Just add a piece of string and the toy is ready to assemble. No batteries, electronics or complicated mechanisms — the spinner is powered entirely by the twisting and untwisting of the string. 🌀 How does it work? The principle is very simple. The string passes through the two holes in the center of the spinner disc. When the string becomes twisted, it stores energy. Pulling the handles apart causes the twisted string to unwind rapidly, making the disc spin at high speed. As the disc continues rotating, the string twists again in the opposite direction. By repeatedly pulling and relaxing the string, the spinner can keep rotating back and forth. The colorful patterns create a fun visual effect while spinning, with each of the three discs producing a different appearance. 🎨 3 Spinner Designs The set includes 3 different disc designs: - Multi-ring geometric pattern

- Radial color pattern

- Swirl / pinwheel pattern

Choose your favorite or print all three and compare their spinning effects. 🪵 Handle Included A dedicated 3D printable handle is included. Instead of holding the string directly with your fingers, the handles provide a more comfortable and secure grip. The groove in the center of the handle is designed as the attachment point for the string. Hold the handles firmly in your hands while operating the spinner. 🧵 Additional Material You will need: String: maximum Ø2 mm Length: approximately 140 cm Pass the string through the two center holes of the spinner disc, then attach the ends to the handles. Make sure the string is securely attached before using the spinner. 🖨 Printing The spinner and handles are designed to be completely 3D printable. You can print the individual sections of the discs in different filament colors to create your own combinations. Bright, contrasting colors are especially effective because the colors visually blend and change while the disc is spinning. ⚠ Safety Before use, always check that the string is securely attached and that the printed parts are not damaged. Use the spinner in an open area and keep it away from the face, fragile objects and other people while it is spinning. ✨ Simple mechanical fun Twist the string. Pull the handles. Watch it spin. A simple mechanism turns twisted string into fast rotational motion — with 3 different discs to choose from and no batteries required.
