This is a medium contico rack I use mainly for yearlings/smaller subadult corns (and hognoses, young pythons, etc - it has a few separate thermostats to each part can be heated to a different specification). Each tub is 39 x 28cm, and 13.5cm high.
I also have a rack made to the same sort of spec, which is large contico boxes (51 x 39cm, and 15cm high). That houses most of my royals. Both of these were made by Winracks
The hatchling rack is a bookcase I bought from Ikea, rear heated. It holds two different sizes of tub. The smaller ones (pictured) are 18.5cm x 12.5cm and 7.5cm high. The larger ones are interstackable with the small tubs, and measure 24.5cm x 18.5cm x 7.5cm.
Most of the larger corns live in front opening 64 litre boxes, like this rack. Each box is 71 x 44cm, and 31cm high. Again this was made by Winracks. I love it - it's so nice not having to pick up and move each box to get in, which with me invariably ends up with spilled water bowls.
That's one of the adult boxes with the front open.
