Converts a ratchet strap into a four corner clamp, so you hold boxes square while glue sets
Works with 1 inch wide straps you already own, so you skip buying expensive clamps
Pulls mitered corners into perfect alignment, so your box joints look sharp and tight
Prints in PLA or ABS for strength you choose, so you build it your way
Designed for workshop use, so you clamp boxes while gluing them together

Stop wrestling with loose corners when you glue boxes together. These corner blocks turn a simple ratcheting tie down strap into a powerful four corner clamp that holds your work square and true.

Thread your 1 inch wide strap through the blocks at each corner. The blocks pull inward as you tighten the strap, pressing all four corners flush at once. This design works especially well with mitered corners, actually pulling them into perfect alignment as you clamp. You get professional results without buying expensive workshop clamps.

Print these blocks in PLA with standard settings, or use ABS for extra strength on heavy projects. The designer tested them on real box builds and found they hold tight through the entire glue cure time.
