Hmm, I'm seriously stuck and it's really frustrating me. At the moment we're pondering about a
new version for the connectors:

It's castable, but it would mean I'd need to redesign the walls, and we'd lose a lot of its modular character: multiple floors become rather difficult, splitting up rooms will be impossible. However, it does mean (a lot) less parts and easy castability.
But on a personal level it then makes me wonder, why bother with this then if I can get a kit by Hirst Arts, Spacestation X or Battle Systems? Or even better, spend that extra buck on a Zone Mortalis table!
It basically means I need to get back to the drawing table and come up with a connector system that (a) maintains the modular character of what I've done so far, (b) doesn't look too obvious and (c) is easy to cast.
In the meantime, to maintain my own sanity, I put some Half Life characters in my previous modular system:
