This earring design was based on Inca and Maya jewelry designs were there are rings inside rings inside.. depicting different gods and symbols. I found these designs intriging and wanted to make them more clean and modern by using geometry.

And if you're wondering about the name, Initium, is the latin word for inception that means a thing inside a thing inside a thing

if you're using Cura, the recommended print sze from my point of view is 0,65.
