Steampunk / Dark Future Mortar System compatible with 28-30mm wargames. Shown with 30mm "waldos" for scale. For "competition" painting, I strongly recommend the Frosted Ultra Detail to minimize cleanup/printing bands/pitting that is the nature of 3D printing. F.U.D. is the default, however less expensive options are available.
EDIT: 6/11/2013 - Apparently White Detail is no longer considered a "printable" material (even though I've gotten it printed in White Detail before) so it's been removed as an option.
