This TriWing 3D snowflake consists of 3 wings - for much better 3D-effect from all sides 360° - and easy print and assembly. There are not many snowflakes out there with 3 parts, so I had to create a new one by modifying an existing one.
This is based on the snowflake (1507757) from 1katkov which consists of 2 wings. I added the 3rd wing in the middle and made the parts thinner.

Remark: Thin extensions of the inner decor into the insertion gap should avoid that the parts fall apart when hanging them up - so don't cut them away.
