A zipper has many issues. The zipper jams. It often gets caught in clothing, making for a painstakingly slow process to fix. It takes a relatively large amount of effort to pull the zipper up and down, a process that often requires two hands. This required effort adds difficulty to the process for children, disabled and elderly. To alleviate the annoyance of a zipper, we have abandoned mechanics of a zipper for the physics of magnetism. Using neodymium magnets carefully spaced and inserted in 3D printed Ninjaflex polymer, The M-Zip is flexible, cannot jam or get caught, is waterproof, and requires minimal effort to “zip up”. Simply bring one side close to the other, and the two attach automatically. The magnets allows for a strong connection between the two sides that cannot easily be pulled apart. It is a solution of efficiency, and simplicity.
