I finally built a couple rodent racks, trying to afford to feed 30-40 snakes a week was proving to get really expensive. I built the whole thing using 2 x 3"s besides the rails that hold the tubs on, those were 2 x 2"s. I'm pretty stoked on them and can't wait to start producing my own food. I figure I'll put 1.4 in each of them, they're fairly large tubs, something like 22 x 28 and 6" deep. With 40 females this could get out of control pretty quickly but I know the guy at the local pet store will buy any excess.
I didn't do step by step pictures but assuming you can get these same concrete mixing tubs, I can give you the dimensions and quantity of the cuts you'll need. If you're not a handy person, would like some racks built and live in Southern California I'll commission a few builds. These things are super tight and super solid, they should last a LONG time
