I made my tubs and attached a j-feeder by cutting out just enough of the hardwire cloth for it to fit through (approx 5-1/2" by 1-3/4").
Here's my version: I couldn't find the Sterilite tubs, so I bought 36gal Rubbermaid tubs with locking lids ($12) and the panels I cut in the sides are 16" x 10". I used a hotknife from Michael's ($16.99) to cut out the panels. I used the 1/2" hardwire cloth (big roll was $8.99), and I bought a 50 foot roll of 19 gauge galvanized steel wire ($2.29) to lace on the hardwire cloth. I bought 5-1/2" j-feeders ($6.50) and 32oz water bottles ($4.50).
