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).
- A beam end dovetailed into the side of a girder, dropped in from above — Japanese framing's standard beam-to-girder joint.
