Opemus 5 M39 Lens Holder (Standard & Deep)

thingiverse

Both are made for a M39 thread (the standard for enlarger lenses). Standard holder - 1mm deeper, allows focus for a bit bigger prints; should fit any lens, including the never Schneiders with the big lever. Deep holder - made especially for a Rodagon WA 40mm lens, so that it fits really deep inside, so that it can be focused to use it to make big enlargements with a normal Opemus column; dunno how it fits other lenses; it has the two holes so that it can fit inside, then you rotate it to be properly held. Prints with supports: on the inside, face-down - makes it prettier; on the outside, face-up - makes the thread print better. Both worked. I printed it with a 0.6mm nozzle, 0.2mm layer. So I guess any normal 0.4n should print great.
