I'm still fiddling with the milk crates. If they were a little bit narrower and a little bit deeper they would make a better base for a rugged "to go" cage.
I did try the 3D-printed shelf brackets from an Etsy shop but they aren't quite what I expected. In looking at them, I realize now that I could cut small square biscuits of wood to fill the grid in the side of the crate and then have a simple rail on the inside and a backing strip on the outside, all secured through the biscuits. I might explore that as it opens up a bit more flexibility in shelf spacing and it's relatively simple and rugged.
