I built already focus and zoom rings for Olympus ZUIKO FT lenses. Recently, I got a request to design and print a focus ring for the ZUIKO 100mm f2.8 prime lens.
Thanks to precise measurements I was able to design and print a well fitting ring in one go. The diamonds pattes is similar to the original design. I am now able to offer a focus ring for this lens as a spare part.
Rubber-like material may only printed in medium gray, the native color of this material. In my opinion, it fits the lens quite well.
