Bring cardboard creations to life with this versatile Spin-Hinge: a simple part that adds smooth, 360° rotation and reliable bracing to doors, windows, trapdoors, wings and spinning features. Designed for quick assembly with a Scru-Driver and Scrus, the Spin-Hinge can be used singly or in pairs to suit small flaps or large panels; attach the fixed half first, punch matching holes in the moving panel, then secure with two Scrus per side to unlock clean swinging and rotating motion. Ideal for hands-on STEM play and imaginative craft-builds, it’s a compact way to introduce moving mechanisms to cardboard engineering projects.
