## Overall (mm)

| length | width | height |
|---|---|---|
| 32.0 | 80.0 | 16.0 |

**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).
- A sliding dovetail mount for accessories: lights, cameras, tool holders, removable trays. The slide can't lift off, only slide.

## Sizes

| dimension | value |
|---|---|
| stock | 20 mm rail on a 4 mm plate |
| parts | rail, slide |
| rail | 13.07 mm at the root → 20 mm at the top, 6 mm tall, 60° sides |
| assembles | the slide slides on from the end |
| holds | the slide on the rail in every direction but along it; add a set screw to lock |

## Questions

**What angle is a dovetail rail?**

60° here (sides at 60° to the base); camera rails use 45°–60°.
