Tree of Life Pendulum

Concepted and modeled for a client. They had them 3D printed through Shapeways in Steel, which was a learning process because apparently the shape of the model (being hollow to reduce cost by 80%) trapped water inside the model during the creation process which caused it to rust.
In the end, they ended up with a printable model that didn't rust and have apparently been getting good usage out of it since then.
