Numbered pawns

Thanks to HunterGreen for the model. This is as much of a "make" as a "remix," but I needed to fix the normals on several of the pawns in order to slice them, so I thought I'd share those files.

I found that the built-in supports didn't work as well for me as those generated by my slicer, so I have just included the copies without support.

I also made [a customizable engraved version](http://www.thingiverse.com/thing:447958), that prints with no support at all.
