80p "Plain" Perimeter Foundation - Fits 80% Model

Plain grey foundation. 5" diameter, 1/4" height. This is a basic, PLA-printed, gray in color perimeter foundation used to represent the original foundation as observed in Drain, Oregon, upon which that burner sits on top. 
     As an additional option, I can add a surface texture similar to that of concrete. I have made this a separate product, so please find that adjacent to this one.
