Vixen to Losmandy dovetail adapter

prusaprinters

Well, I bought a used OTA without really looking at the dovetail style until two days before I planned to use it. I couldn't find anything at a reasonable price, let alone anything that would arrive in time. So I decided to design an adapter to get me by until I could purchase a proper adapter or saddle.This adapter uses M4 hardware. 14mm long screws for attaching the clamp to the Vixen dovetail, and 20mm long screws for the clamp part of the adapter. The nuts are all press fit. The mating surfaces may need some finishing to allow easy movement, but it has plenty of tolerance built in. The nut recesses and screw holes/counterbores are pretty tight. I ended up drilling out the holes in the clamp parts to allow more free movement. You'll need to print one Vixen bar and 2x Losmandy shoe and Losmandy clamp. I printed with 0.6mm nozzle, 5 shells, 6 top and 6 bottom, shooting for 3mm wall thickness. I used 20% infill. However, print in the manner you prefer. I find that printing with thicker walls produces a stronger part.
