Canon 100mm F2.8 focus gear

I love focus pullers, but I despise those adjustable rings that come with them. So, I decided to make some focus rings to stick on my lenses and have them there forever. These rings look perfect and work flawlessly. They are 3mm thick, just like all the ones on my account. They were designed specifically for the Zhiyun Crane 2. I used a gear tooth calculator online at scriptasylum.com to get started, then refined the design with a Windows app from forestmoon.com. I'd like to thank the person who started this motion at youtube.com for their inspiration. Now, I've printed rings for all my lenses. Happy printing!
