Built mine from a pile of discounted/discards 2x3's I picked up at Home Depot or Lowe's. Had them cut to my specifications, cutting out the bad spots that discounted the wood. I paid $1.90 per board with each board being about 16 feet in length.
There are four "shelves" with a 12 inch vertical gap between each shelf. Each shelf is made of 4 pieces of wood: Two pieces 5 feet in length and two pieces 9 inches in length. The smaller pieces act as caps on the longer pieces (so the insides of the longer pieces are 5 inches apart) with both longer and shorter pieces being used standing on end (3 inches tall, 2 inches wide). The boards of each shelf are glued together.
The four shelves are held together by four "legs" (risers/columns). Each leg is 48 inches tall (3 inches for each shelf times four shelves and and 3 twelve inch gaps between each shelf). The bottom of the feet and the bottom of the lowest shelf are both flush with the floor.
Pre-drilled two holes through each intersection of leg and shelf for a total of 32 holes. I used a 5 inch bolt with two washers and a wing nut through each hole. Use a level on the second, third, and fourth shelves. This way, you can take the whole unit apart if you want to. Otherwise, you could use wood screws and glue.
Each shelf holds 5 balls for a total of 20 balls.
Wood, bolts, washers, wingnuts, glue ... All total it cost me about $20 to build.
