Useful Clamps

Very good for holding box corners in place, easier than using weights. Good strong magnets.

Set of four 90-degree magnetic corner clamps for bookbinding, boxmaking, and other crafts and hobbies. The set includes four outer parts, four inner parts, and one straight part (see the first photo for reference) of the chosen size and height.

3d-printed with PLA plastic, the clamps have neodymium magnets safely embedded within the plastic. Tested with 3-mm-thick cardboard, but should hold against an even thicker material.

The clamps are available in several variations:
- small 40x40 mm, 10 mm high - weaker magnetic force (not recommended for cardboard thicker than 1.5-2 mm)
- small 40x40 mm, 18 mm high
- large 50x50 mm, 10 mm high
- large 50x50 mm, 18 mm high - the strongest magnetic force among these clamps

Warning: large double-level clamps are really strong, so to avoid damage, we recommend pulling them sideways rather than just straightforwardly taking them apart.

The set was updated to meet the safety standards related to small magnetic items.

If you'd like to get other sizes, shapes, or angles, please make a request for customization.

By default, our jigs and tools are printed in any random color available at the moment. If you want to choose a specific color, please message us.
