http://www.shapeways.com/model/1151697/0805-leds-front.html I will do some kind of black. It is to isolate LED lights from each other for a spectrum analyzer. The smaller space between each element is 0.75mm. It doesn't need to be super accurate. It also doesn't need to be strong because it will be epoxied onto a PCB and the holes will all be filled with epoxy. Then the face will be ground flat. It will become a solid object. Should I use strong & flexible or detail?
