This is a sleek and modern ring design inspired by the pentagram motif, perfect for 3D printing enthusiasts. The open structure gives it a unique aesthetic while ensuring a comfortable fit. Designed for a size 18 ring, it can be resized to other sizes using slicing software.
It is designed to accommodate a gemstone measuring 4 or 5 mm in the designated slot. Use a very strong adhesive to secure the stone in place.

I also added the version without gemstone.
