"Plain" Perimeter Foundation - Fits Full Size HO Model

Plain grey foundation. 5 & 7/8ths diameter, 3/8" height. This is the same perimeter foundation included in the HO scale kit.  This is a basic, PLA-printed, gray in color perimeter foundation used to represent the original foundation as observed in Drain, Oregon. The burner sits on top of it. 
     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.
