  • Mobius zipper interactive teaching and learning device
    Patent number: 11670192
    Abstract: A mobius zipper learning model is described. The learning model can include a device comprising two 3D printed, hard plastic, semi-circular halves connected by a plastic zipper, which could also be 3D printed, with top ends connected to the frame halves. The zipper can be twisted and then reconnected at the bottom of the frames using embedded fasteners (e.g., hook and eyelet, snaps, or hook and loop). The Mobius zipper permits topologists and others to explore and demonstrate Mobius properties without having to seek and size workable material (usually paper) and/or successfully slice the selected material. Further, use of the Mobius Zipper results in no waste of material.
