Summary As a FYI There is a License agreement with this Download and If you do download these STL file you are agreeing to the license. My dog likes to chew on the glass in the fireplace so I build this cover to keep the Dog out. I used 1/8 inch Plexiglas from Home Depot and Made these brackets and clips to hold in place. There is about 1/4 spacing on all sides. I printed this with a 0 support and had to file the piece to clean it up which didn't take too long. The clips need light filing as well.
