Here it comes my another project!
I'm 'retired' biomedical engineer so anatomical structure were always following me. Maybe that was the reason why i decided to make spine shaped necklace.
This project is very special to me, because it was my first adventure with Blender :)

This particular models don't have to be used as a necklace, so if you need a blender file to edit or modify the models, just comment below :)

There are 5 types of shapes: initial ( with chain provider), final one ( spiky) and three middle ones with various length or 'arms'. Scale them up as you wish :)
For printing i have used a silver PLA, layer thickness was 0.1mm and infill 10%
