What if you could assemble your house like Legos using free modeling software and a 3D printer? That’s the idea behind Eric Schimelpfening‘s WikiHouse – a home designed entirely in SketchUp that can be downloaded by anyone, customized to fit the user’s needs and sent to the 3D printer. The components are then snapped together using less than 100 screws to make rooms that can be rearranged as easily as you would rearrange furniture.
