Are you wondering about the possibility of 3D printing your own miniatures? There are free 3D files for almost anything now. Even your favorite wargame miniatures are coming to an open source database near you.
Out of simple curiosity, I did an online search for free 3D printable files for Warhammer 40k and Forgeworld models. I discovered a plethora of Warhammer-inspired work from the 3D modeling community. All of them are downloadable, and can be 3D printed without much post-processing work. Easy!
