Alright folks, are you a 3d model builder? Or have you found a 3d model you want to recreate in Minecraft? Well, you're in luck! erich666 had his friend Patrick Min created the 3d modelconverterprogram so you can do just that!So, if you have a 3d model of a chair. You can use that program and get the blueprints required. It's really easy and it's free. It doesn't get any better than this, folks.
I recently got Patrick Min hooked on Minecraft. Among other things, he's modified his voxelization programs to help you convert any 3D model to cubes and build it in Minecraft (by hand - anything else is cheating ).
Go to his web page and enjoy; he's very open to suggestions to improve the software (links to binvox and viewvox are in the upper left of this page). Also, it's all open source, and works on Windows, Mac, and Linux. I have a post further down in this thread that gives a tutorial.
Here's a project I built in a few hours (more screenshots here):
