This is a ring with hearts on the side. I made it in solid edge hence the .par file.

This ring prints very fast and made an excellent thing to introduce the skeptical significant other to 3d printing with by having her watch the whole process.

This ring is sized to 19mm, I just experimented with the scaling in slic3r and printed a bunch of different sized rings scaled 100%-120% to find ones that fit.

The hearts were easily visible even with 0.15-0.20mm layer height.
