Ok, I don't generally do the kickstarter thing due. But, this one I may pull the trigger on!

Now if they can roll out iron and aluminum too

I kinda would like a lead looking mat. I think it would be neat to 3D print some ammo (no, not to really shoot, for jewelery and keychains). With the brass and copper here, that gives some opportunity. With lead, that adds to the possibilities.

Curious how conductive these are. And if the copper would be solderable. If both pass muster, I can see 3D electronics going on here. Print up some halloween costume parts with imbedded circuitry for lighting/sound. Interesting idea eh?
