Samyang 135 lens holder and manual focuser

thingiverse

Another lens holder for the popular Samyang 135 f/2 lens with manual fine focusing. The rings accept M6 nuts to connect to a dovetail bar and the finder holder on top. The upper and lower parts of the rings are connected at the hinge via M4 screws and self-locking nuts. The opposite side accepts M5 nuts, if you want star handles, use socket screws and also print "Sterngriff". The fine focuser screws and fastener for the finder are also M4. There are no nuts used here, the print already includes threads, but they should be tapped afterwards. For the fine focuser use 25 mm with complete thread. I added a cap nut as you can see. Again, if you like the star handles, use socket screws. The fine focuser ring is a bit too small, it needs to be opened for repositioning. You may want to print this a little larger. I still need to figure out the perfect size. The lens provides only little space for the rings, thus they are quite thin, leading to narrow walls around the nuts. Be careful when inserting, especially the M6 nuts.
