The Samurai Amulet from Power Rangers Ninja Storm. This model has been broken up into three seperate parts to make painting each section of the finished prop a little easier. You could also print each section with the appropriately colored material to avoiding painting altogether.
The four outer sections were not designed to be a friction fit within the body section. There has been enough of a tolerance given to allow for a couple laters of primer and paint and you will have to use an adhesive to attach the parts to each other.
