Hope you get as much inspiration as I have found here, I love the way Zach has marketed his models he has found a unique strategy for getting his product to the masses. Take a look at some of the other files that others have made as well by browsing the Lab and most importantly have fun
Hi Thiery, glad you made it over here! Be sure out check out the Members Section if you're interested in the fan made stuff. Rob Heath (Sun Tzu here) has contributed a large number of really well made mods of my basic models. I'm currently working on a 1:1 scale model palace, a modular castle system, a second cathedral, and a few other things besides. Also, if you know anyone else who is interested in 2mm or micro-scale minis, let them know about us!
As regards 3mm, if you go that route you can still use my buildings. Just print them at 150% of the default size and they'll be in 3mm scale.
