Here is another set of platforms to use with your favorite figurines. I created those with ZBrushCore and i used Fusion 360 to make sure the models had no errors.

Added 3 more platforms (manhole covers + steampunk theme)
I sliced each file in Simplify3D at 0.1mm layer height and all the details are kept on my Wanhao I3 V2.1 FDM printer.
