Hello everyone
I saw a mechanical ring on the Internet. Personally, I was interested in all the projects I did because they were mechanical systems. I found a video on making it. Click for the link of the video. I wanted to design this ring using xDesign and I designed the ring in the video. 

After the final design, I will try to print it using a 3D printer. It will be difficult to print with an FDM printer as it is a ring but I will scale up to see the mechanism work.

Since I will be producing on a 3D printer, I left working gaps.
I facilitated the movement of the gears by leaving a 0.25 mm working clearance.
The clearance in the locking mechanism is 0.15 mm. I fixed it with a tight fit.

An engineer's understanding of romance could only be demonstrated by a mechanical ring.😀
