This is a DXF file for a portable, snap together fire pit. I designed it for use when camping or when limited on space. When disassembled the complete fire pit is only 12 x 35 x 1.5. This fire pit snaps together in under a minute with no tools or fasteners. When assembled its approximately 35 x 35 x 12 tall. A DXF file is the file needed to cut this out of steel on a CNC plasma or laser. Cut it yourself or find someone local that can cut it for you. Fire pit can be completely cut out of one sheet of 1/8 steel (11 gauge).
