Simple ring design with a minimalist approach: print the same element in different colors and combine them in pairs (or more, if you like) to match the ring with your outfit or mood!

I've included the Fusion360 file so you can easily modify the inner diameter (check the file Parameters, they're self explanatory) and have the perfect fit.

The included file has an internal diameter of 17.2 mm.
The open loop design allows some degree of natural adjustment.

It prints without supports.
I've printed mine with 0.12 LH and 100% infill.
I suggest to print two at a time to help with cooling.
