This is a do-over of one of my most popular designs. The cipher ring is now a bracelet!

This is sized with a 70mm inside diameter. That's a customizable parameter in the .scad file. After assembling the rings onto the main body, there is a retaining ring that should twist into a locked position. (One of the .pngs shows the final step.)

My printer is currently broken so I haven't been able to print a prototype to check for fit and/or assembly problems. If anyone in the community could print one off and let me know how it turns out I'd be appreciative! I'm particularly wondering if the final assembly of the retaining ring will go smoothly...
