Unfortunately the only box I've found was "UPPRYMD", which is exactly the Detolf's dimensions but sold only in this cat pattern. I'm a woman with cats so I can get away with the cutesy pattern, but you will probably want to either dye it or find an alternative.
Basically get a milk crate and something to cover it. Or get a 1x1 Kallax or something similar if you find any place that sells it.
