Magnetic Locking Box

cults3d

Magnetic lock box utilizes magnets for its hinge and keyed lock mechanism. There are two versions available, with the locking box requiring a ferromagnetic filament to function (similar to ProtoPasta's Magnetic Iron Filament). The non-locking box, on the other hand, can be used with regular filaments. I've always been curious about whether this concept would work, even though I don't have a specific use case for it. The hinge is designed around 4mm cylinder magnets, which serve as the axis of the hinge. By reversing the polarity of each magnet (north to north, south to south), you can create a spring-like mechanism that works as the hinge. You can see the 4mm x 10mm cylinder magnets inside the hinge in one of the pictures above. Shorter magnets will also work, but more of them may be needed. In the magnetic iron box, the hinge can be made with just two magnets since they'll attach to the side of the box. However, using more magnets as described above provides greater security. The lock uses 3-4x4mm cylinder magnets, which are normally recessed in the lid but get pulled to the edge of the box when the key is placed over the lock in the correct position. This locks the lid in place, even after the key is removed. To open the box, you can hold the key in the open position against the box or press on the back of the lid. The key itself uses 6-4x4mm cylinder magnets (with two magnets per slot). The magnets should be inserted into the key to match the polarity of the lock when it's in the locked position and may need to be glued in place. You can customize the design by changing its size or the types of magnets used through Onshape, a 3D CAD platform.
