## Overall (mm)

| length | width | height |
|---|---|---|
| 80.0 | 60.0 | 20.0 |

**Exact dimensions.** True size, with no printing tolerance added.

## 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 slotted end straddles the through member, which is cut down to its middle third where they meet.

## Sizes

| dimension | value |
|---|---|
| stock | 20 × 20 mm square |
| parts | through member, slotted member |
| middle third | 6.67 mm |
| slot length | 20 mm |
| assembles | the slot straddles the through member from the side |
| holds | racking and twisting; pin it against sliding |

## Questions

**Where is a tee bridle used?**

Where a leg or rail meets a long member mid-span, e.g. a table leg under a long rail.
