fidget toy 3d model

3D printable modular fidget toy inspired by a “Tangle”, designed for children aged 4–7. Generate the toy as separate individual segments, not as one single merged object. The design must include 6 detachable curved segments, each as an independent printable part, with compatible snap-fit or ball-and-socket connectors on both ends so they can be assembled and disassembled easily. Each segment must have a different tactile texture suitable for sensory play: 1. smooth surface 2. rounded bubble bumps 3. ribbed texture 4. small raised dots 5. fabric-like embossed texture 6. foam-like geometric texture All parts must be child-safe, with fully rounded edges, no sharp corners, and soft ergonomic curves. Optimize every piece for FDM 3D printing: * printable as separate parts * watertight mesh * minimal supports * no overhangs above 45 degrees * wall thickness 2–3 mm or lightweight solid Each segment should be similar in size and proportion, forming together an assembled toy of about 12–15 cm total length.
