Vixen-style dovetail clamp
thingiverse
This was designed for attaching lightweight accessories, like a finder or guide scope to a Vixen-style dovetail plate. Assemble with two 1-1/4" 8-32 cap head screws and 8-32 square nuts. The attachment hole locations are set via the screw_holes array in the .scad file. The default in the scad and stl files is four attachment holes, as shown in the stl rendering, but the one I printed only has the two holes shown in the photos. This is sized for and has been tested with a V-style dovetail plate. It should be possible to adapt to a Losmandy D-style dovetail plate by appropriate settings of the dovetail bar parameters is the .scad file.
