The 3D core sounds a natural extension to laser cut part, brass gun barrels and photo etching, not every ones cup of tea but useful. I personally like the vents and winches, something I have been playing with in my very rare spare time. as Herky said cost to the the rest of the world is high, any chance in selling the stl files to those who have 3D printer access, or find some on to market them down here?
