Flat Open Bracelet

I'm 48 minutes (my local time) late for my thing-a-day! Finally, here it is.

It's a flat (boring?) oval (can be perfectly circular too) open (of course, you can close it) asimetrical (thinner at the open side) bracelet (or ring if you make it smaller).

This design is intended to be an envelope to be boolean used (intersection) with other textured designs, we'll see...
