A clip that can fit on a key chain or bag, with a relief of the renowned theoretical physicist Albert Einstein. 

Using any layer height is fine, but the lower the better to ensure that the detail of the relief of the face. The 3mf file has each file separate, along with a modifier box on the handle 

Used the base tag from my model (GPL-v3).

Used the face from iczfirz's “Albert Einstein Support Free" (CC-BY-SA) for the relief.
