A very basic procedural ring designed in Blender. The `simple procedural ring.blend` file is square, but should work no matter what extreme values you input. Any layer height should work. The `procedural ring.blend` file gives you curved edges, but does have limits where it breaks. I'd recommend printing at 0.08mm layers, as it makes the curves super smooth.

Both are written in Blender 3.6.2.

The rings are incredibly easy to stripe via layer changes. I print them on my P1P without a brim on the flat PEI bed(High Temp Plate). They're comfortable enough to be worn daily in my experience.
