I designed this just for fun but they actually work quite well also. I was interested in seeing how to print two components together without them bonding. I used a 0.2mm print layer and a 0.2mm gap between the two rings. They stick together but don't fuse together and can be pried apart quite easily and then after that they are like a normal split ring The rings are 20mm, 30mm, 40mm and 50mm inside diameter. The smaller rings are definitely stronger but all are useable. I printed them all as one set and it worked well. But I am including individual rings in case you don't want them all. Take note of the print settings though, they will be particularly important if printing one ring at a time. More information about this design. and many many more, on my blog site...  https://logicalplant.com Print Settings Printer: JGAurora A3S Rafts: No Supports: No Resolution: 0.4mm nozzle, 0.2mm layer height Infill: 100% Filament_material: PLA Notes: I set the nozzle temp to 210 to ensure good fusing where desired, and then used the following settings to ensure a slow print so that the two layers of the split ring don't fuse together... Print Speed: 50mm/s Minimum Layer Time: 10s Minimum Speed: 10mm/s Post-Printing, Splitting the ring Once printed, lay on a flat surface and pry under the end of one of the coils. I used a small knife blade. Once you pry the end up slightly it will separate quite easily.
