I just wanted to make a quick arch test with my filaments but I decided along the way that I wanted a little design on top.

Fu (Fuku) → Good luck

Lu (Roku) → Prosperity

Shou (Ju) → Longevity

They weigh 1g each.

The rings itself is imperfect so I left the fusion 360 files in case you're more experimented with jewelry 3d printing than me or you just want the symbols.

I also tried designing it as a signet ring but I couldn't make it work.

If you want a different size but don't have a CAD software, you can ask me and I'll bring the modification.

I printed face down, no support or brim.
