Overall (mm): length 80.0, width 80.0, height 20.0
- Woodworking joint drawn for 3D printing: the parts lock together by shape, so a print can be joined without glue or screws. Drawn at true size with the parts line to line (zero gap) in their assembled position — add your printer's fit allowance to the mating faces (your AI or slicer can do this).
- The tenon's hole is offset toward the shoulder, so driving the peg pulls the joint tight — no clamps or glue.
- The peg overlaps the tenon by the 1 mm drawbore offset on purpose: that overlap is what pulls the joint tight.
