Notes

  • 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 stock is split in thirds: the tenon is the middle third, the slot leaves two cheeks of one third each.
  • Prints well: both parts flat, slot and tenon in the plane of the bed.
