Instructions
Purchase a metal cash box or a similar small, sturdy metal box with a latch. For most purposes, you'll need a metal box that's about 10 or 12 inches wide, 4 or 5 inches tall, and about 6 inches deep.
Don safety glasses to prevent eye injuries from metal shards that may result from the drilling and filing process.
Use a drill with a bit suitable for drilling holes in metal to create one or two large holes on the lid of the box. The bit is large and circular, with teeth around the edge of the circle. The number and size of the holes will vary depending on whether the box has a handle and the size/location of the handle. If drilling just one hole, a diameter of 4 or 5 inches is sufficient; if drilling two holes, use a bit with a 2- to 3-inch diameter.
Eliminate the sharp edges of the hole using a dremel tool with a metal file attachment. File the perimeter of the hole(s) to prevent injury to the dog's nose and anyone who handles the box.
Cut a piece of screening that's slightly larger than the hole(s) that were created in the box top.
Open the box's lid and place a bead of epoxy glue around the perimeter of the hole(s), about 1/4 to 1/2 inch from the edge of the hole. The glue will be placed on the underside of the lid, so when the box is closed, the glue will not be visible.
Place the screening over the holes on the underside of the lid and sink the screening into the glue. Allow it to set, per the instructions on the glue packaging. Setting time varies by product.
