Ring designed for 3 years old child.
I used Meshmixer to create tree support (in addition) for printing model in vertical position: https://www.youtube.com/watch?v=OXFKVmMwXCQ
P.S. For the top emblem can be used filament that glow in dark. Make you children happy!
The author marked this model as their own original creation. Imported from Thingiverse.
