Cool skull keychain, using the model by LeFabShop.

For best results print with supports, 25% infill, and .2mm layers. The high infill helps support the overhang of the rounded head.

An extra file is provided with an added base to the keychain. I found that printing this helped it stick, as it is such a small model.

I added a torus and a rectangle base to the skull using 123D Design.
