brock split ring for keys

I created this project purely for entertainment purposes but surprisingly found that it also worked quite effectively. I wanted to experiment with printing two components together without having them bond into a single unit. To achieve this, I used a 0.2mm print layer and maintained a 0.2mm gap between the two rings. As expected, they stuck together but didn't fuse together, making it relatively easy to pry them apart. The four rings have inside diameters of 20mm, 30mm, 40mm, and 50mm. While the smaller rings proved to be stronger, all of them are usable. To print these rings efficiently, I printed them all as a single set, which worked out well. However, I've included individual rings in case you prefer not to have them all. Be sure to take note of the specified print settings, as they will be crucial if printing one ring at a time. Note the following print settings:
