Wire Shelf Bracket for Hexagonal Greenhouse

With a new small greenhouse and a big garden to start, I needed a way to add shelves to the greenhouse without sacrificing floor space.
These supports are custom designed to be used with wire shelving purchased from a big box store and a hexagonal greenhouse constructed with aluminum extrusion (Palram Oasis). The shelves are cut at the appropriate angle with bolt cutters and slot into the sides of the brackets, secured with zip ties through the printed holes. The brackets are held to the corner posts with T-bolts.
There are 3 versions, a left and right version for the ends that only have the shelf slot on one side, and a middle version that has slots on both sides. Small center supports were used at the midpoint of the shelves to provide additional support on the back so they could support full planting trays.
