Instructions

This is made from 3/4 Schedule 40 PVC. Get it from your big box home improvement store. There are no exact measurements here. You will need 6 90° elbows and 2 tee joints. Use 6 lengths of PVC joined by 4 elbows at the corners and the tee joints on each side. Out of the tee joints comes two more lengths with the other two elbows. Then there is one more length at the top. I would not glue anything. It is very sturdy and I like mine to come apart. My particular build was about $10 and took around 12' of PVC. YMMV.
