Into The Radius Regen Artifact

This is the rough shape of the Regen Artifact from Into The Radius. I don't think  its 100% right, but looks similar. I'm planning on printing a multi-color version to have some of the dark edges from the game and will update if it works out. 

I recommend a number of perimeters to increase the weight for a better feeling in the hand, as well as to align the lines for the top couple of layers. A variable layer height can be used to make the top surface quite smooth even at the shallow angles.
