I hope this pendant helps to add to the spirit of unity this holiday season. I used Ogham script from the Celtic culture of the same origin as the ancient symbol the design is based off to add a holiday unity message. The bars across the spiral spell “All are one (In English).” I designed this from the ancient design some say was a pre-cursory to the trinity to fit the unity message. (I did not start from anyone else's material. It is a common ancient symbol.)
I recommend converting the scale to mm and then scaling to 200%. The file is quite large. You may get an error about non-manifold edges. It printed fine for me without repair and without supports.
