Vixen Dovetail Adaptor for Samyang/Rokinon 135MM F2 lens

thingiverse

This is a two ring adaptor and dovetail plate for a Samyang/Rokinon 135mm F2 lens. The dovetail and rings are joined with M4 bolts and the lens is secured in the rings with two M6 nylon bolts, do not over-tighten the front (large ring) nylon bolt as it stops the focus ring from moving. You can print the rings upright or lying down. You will get better M6 threads if you print upright, but you can always use an M6 tap afterwards to polish the threads. I printed in PLA on ender 3 v2, extruder 208 deg, bed 65 deg, 0.4 nozzle (all else standard).
