Plywood Quick Corner Clamps (2nd set of hands)

thingiverse

Update: Added versions of the 3/4" one, including a 1mm chamfer version and a thickened wall version with a 6mm thickness. The 3/4" thickened wall version is chamfered for easier assembly. A fourth version adds increased spacing between the clamps to 23/32" (0.7185") for tighter fits. These are 90 degree clamps designed specifically for box, cabinet, and shelf joinery using 3/4 ply (0.70" thickness). I drew inspiration from a popular name brand wood working product that uses plastic components. Four of these clamps sell for $10, but I was able to create my own version with just $0.10 worth of material. One side can be adjusted to pass through only, creating a T Joint (shelf) instead of an L Joint (corner top/bottom). This design is currently optimized for 3/4" ply (0.70"), but I will soon release a version for 1/2" ply (12mm). To print these clamps, simply slice the model and mirror it to create all necessary parts. Print at least four clamps, but eight are recommended. The sidewalls and bottom of each clamp are 4mm thick. If you have suggestions or requests for changes, please let me know via comments.
