Customization pack for 8-bit Videogame Coasters by hockenmaier

That's just a openSCAD package to make your own design for this 8-bit videogame coasters http://www.thingiverse.com/thing:115150.
Came with a few examples.

If you couldn't find the character you like, just design it.

TODO: I'm having troubles with pictures who have holes on them. I'll try to fix it.
