Shapeways does 3D printing in steel, brass, bronze, silver (in addition to plastics). Can even get them with polished, matte, polished gold finishes. So I've been learning sketchup and trying to draw models for the parts. I was going to get them printed in plastic first to double check all the measurements before getting metal ones printed. I've got the string block, bridge block and string tree modeled (below). Was working on a jaguar style knob so I could get some printed in white; but I found a supplier that has them for much cheaper than it would cost to print.
To print, the string block costs $37 in polished steel, 83 in polished brass
Bridge block: 55 in steel, 125 in brass
string tree: 20 in steel, 45 in brass
(I'm not affiliated with shapeways, nor are my models available to get printed right now; just giving you an idea of the costs)
I'll likely make the models publicly available on shapeways after I double-check the plastic models.
