This is my first post ever on Reddit. For the past 2 years I have been wearing a unique metal chastity device which, in my opinion, solves the problem of urine smell. I would like to improve the locking mechanism from a hex screw to a real lock with a key. I think a 3D printer is the way to go, however I don't have a 3D printer and don't know how to use any application to create a 3D design.

A sketch of my design

This is an actual picture of the device I have been wearing for 2 years, however want to slightly change the sizes of the rings. I lost contact of the person who made it.

This is how the device is currently being used on m. Notice the urine does not touch the device which makes the process easier to clean.

Anyone making such a device? By the way, if you know a store already making such a device, please let me know.
