Overall (mm): length 160.0, width 200.0, height 10.0
- 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 cap across the end of a panel: the centre peg fixes it, the outer pegs sit in slots so the panel can move. For prints, the same trick lets a long part expand without cracking its frame.
