That die-cast aluminium box with 3/8 " wall thickness is difficult to find. I have been using Weidmüller Klippon boxes that come with about 5 mm wall thickness. One could try to use a smaller one inside a bigger one.

Today will be probably cheaper to cut aluminum plates and screw them together. On the other hand why not to use thicker steel like imo on university. Main downside is weight, but material is easier to get and cheaper (on scrapyard, maybe even suitable box can be found) and thinner copper box can be inserted if needed.
