Super Takumar Follow focus rings

thingiverse

This is a 2 piece design of follow focus rings for a couple of takumar lenses. I have a pretty complete collection so as I design and test more I will add them. In this set is 2 80mm focus ring designs with the correct specs for any follow focus system you use. It was tested with a Tilta Nucleus. The V3 design has an opening on 2 sides for a M4x4mm set screw to help hold it in on the inner ring. The V4 design does not have this incase you just want to press fit it or glue it on. I designed them as 2 pieces so that you can easily swap the outer ring in the event of an accident. You can swap outer rings from 1 lens to the other without needing to print a whole new piece. This also cuts down print time on each piece. On my printer I can print an outer or inner ring in about an hour. Some sanding might be required depending on the tolerance of your printer. The lenses included are listed 28mm F3.5 35mmF2 (with M5 threaded openings for set screws) 55mm F1.8 85mmF1.8(with M5 threaded openings for set screws) 105mmF2.8 2 of these lenses include threaded openings for set screws as I originally wanted to add the ability to help hold them onto the lense in a more secure fashion. They arent really necessary as the tight fit holds them securely enough.
