Miter Clamping Cauls - 3D Printable STL File

Achieve precise and clean miter joints with these versatile clamping cauls. Designed for both standard 45° miters and non-standard or unknown angles, they fill a gap that traditional clamps and cauls cannot — making them an essential addition to any woodworking setup.

The open lattice structure keeps material use low without compromising rigidity, and the cylindrical clamp interfaces allow standard one-hand clamps to apply force cleanly and consistently along the joint line.

What's included

This listing includes 2 STL files and an accompanying assembly and usage guide. One file contains the standard version, the other features additional support around the cylindrical clamp interface
