Dovetail rail and slide mount (60°)

What is a dovetail rail mount? · Hardware · basis: Xem Studio design — geometry computed in the generator from traditional proportions

Also called: dovetail rail, dovetail mount, dovetail slide 3d print, accessory rail, sliding mount, riel cola de milano, Schwalbenschwanzführung

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.

What angle is a dovetail rail?

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