This is a raised bed garden corner bracket. You need 2 of these at each corner. I designed this such that you can use cheap Cedar Fence material you can buy from Home Depot for ~$2/each. The hole is designed for a 1" diameter schedule 40 PVC pipe. Just cut it to length, put a diagonal cut on one end to make a sharp point, then use that as a stake. You can stack these brackets so that the bed is deeper. I've seen commercial versions of these brackets sell at Home Depot for $14/pair that use 2x6 wood. These brackets use about .2 lbs of ABS, so you can print out 4 pairs for about the same price (I buy ABS for around $20/2 lbs on the internet).
