Flexible Ring with Airflow

Remixed version of Ready4Anarchy's "Men's hex knurled ring" but with airflow channels on the inside to improve breathability.

Printed this in TPU and it flexes like a silicone, but is more rigid, reducing the irritation you can get from silicone bands.

For sizing reference, I'm a 7.5 and when I size this to 24mm in Cura it fits great.

I'm new to this and can't seem to figure out how to add a remix to Ready4Anarchy's original page, so, if anyone knows, please tell me.
