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).
- Two boards slotted halfway, one from each edge, so they cross flush — dividers, grids, organisers, and flat-pack frames.
Egg crate joint size chart
| dimension | value |
|---|---|
| stock | 10 mm boards, 60 mm wide |
| parts | board a, board b |
| slots | 10 mm wide (the board), 30 mm deep (half the width) |
| assembles | B slides down onto A |
| holds | the boards square to each other; makes grids, dividers and box inserts |
