Hi! Yes, I use this design currently for my colony of Camponotus sp. and Messor barbarus, together with a bunch of the other Modules I've designed, like the vertical helper and the large nest modules :) I'm currently planning an improved version with sizes of approx. 25x25 and 15x15. The original design has already some not-yet-released upgrades like optional heating-element mounts for more exotic inhabitants.
