- 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 rabbeted tongue on one board in a dado in the other: stronger and better located than a plain rabbet — cabinets and drawer backs.
