Found these at https://facepunch.com/showthread.php?t=1304034&page=6

Also found AnyCad converter with the click of a button turned them straight into .OBJ and .STL's http://www.anycad.net/the-free-3d-model-converter-anycad-exchange3d.html

Always with the dream of slicing them up to print, but with so may cool projects in the pipe line, I'm not sure when that will be. As with all these untested prints, Please venture at your own risk : )

Here they are for all to enjoy. Any credit should go to the author at facepunch.com
