Cubecus is here! After a long time coming (4 years on and off), I've gotten my Blender level design add-on into a releasable state (even though in alpha and with some glitches). Don't worry though! It's going to get better with more releases where I plan to separate out the obfuscator it uses into a separate project and add more features and fixes.

If you're unfamiliar, give it's page a look. It explains about the different tools it adds and provides screenshots of use (like the one below).

I hope that everyone who's asked about it and even those who've not, find it useful :)
