Hazard Symbol Miniature Bases

These are miniature bases for tabletop war games. Diameters are 25mm, 40mm, and 60mm. The original set includes all versions with 4mm platform height + 1mm design height. Includes the radiation symbol and the biohazard symbol in all sizes, and a crude 25mm skull-and-crossbones "bonus" for your entertainment.

UPDATE 26 May 2013: Individual 25mm versions are 3.2mm platform height to match my other base designs. Also uploaded here: http://www.thingiverse.com/thing:90269
