This site is home to a growing collection of printable scale minis, sometimes known as "printies". You'll find everything from foldable computers to stained glass windows. They're here for you to print for free on your color ink-jet printer.
I love these things because my Father used to make dollshouses & furniture & fittings for them out of bits of everyday things - I recall him painstakingly cutting brick shapes from the sides of matchboxes for the external brickwork. So much patience!
