Re: [sudo-discuss] anti-surveillance mask

Hmm... Shapeways' 3D printed "full color sandstone<http://www.shapeways.com/materials/full-color-sandstone?li=nav… "? Needs to be a minimum of 2mm thick, so if you're making a 20cm x 20cm mask, that would come out around $60 or so. This stuff is pretty fragile (there's a reason it's called full color *sandstone*), so you'd probably want to coat or impregnate it with something that'll give it more strength. Or you could just print on paper - much easier and cheaper. Does anyone know of a flexible rubber sheet material that can be inkjet printed? That would be the next best thing, I guess.
