Industrial Corner Shelf

Ever wanted a really big corner shelf to put junk on? Don't want something that looks good? This shelf is for you! I spent about a week designing this, including printing the whole thing out only to realize I had screwed up probably 10 or 20 things and ended up trashing my whole approach and remaking it - over and over. So much work for what is essentially half a cube and two planes. The structure is made such that the strut running up through the top shelf from the bottom shelf is under tension and supports both shelves. I used pins to attach the lower shelf to the lower strut, and more pins to simultaneously hold the two back panels together and secure the upper strut. Everything needs glue or it'll fall apart in your hands: Glue the struts. Glue the pins. Glue the struts to the shelves. Glue your hand to the shelf.Screw the whole construction to the wall. Don't use glue for that. There are little holes in the top and bottom of the lower and upper struts, respectively. Yo
