Shelf Extension Support

My wife asked me to extend the depth of the top shelf in our closet. Without completely removing the panel and installing a new one I was left with adding a thin piece of wood, but I knew it needed support to prevent sagging and failure. These are relatively quick prints that require no supports. They snap-on to a hanger rod providing stability to a shelf that extends beyond support of a hanging rod bracket. There are two different versions, each with two types.Support Double - 25mm - fits centered on the hanging rod on either side of the shelf bracketSupport Single - 25mm - fits anywhere else. These are a narrower version meant to provide similar support where you still need to bridge large gaps that may sag, but there is no shelf bracket to contend with.Support Double - 22mm - Same as 25mm, but fits on the smaller side of the telescoping rod.Support Single - 22mm - Same as 25mm, but fits on the smaller side of the telescoping rod.
