Perimeter Foundation - Fits "80P" 80%-size Burner

Gray foundation. 5" diameter, 1/4" height to fit the 80P-sized burner. PLA-printed, gray in color. You choose whether you want the plain-PLA surface or if you want it finished and weathered in a “concrete” textured version. This is the foundation modeled as I learned of it on the burner which is located at Drain, Oregon. I am sure there are other versions out there.
