Do you need a quick prototype parts? Do you want to test the part design before you put down the cash to mill it out of metal? Why not 3D print it? I put this part in my 3D printer before I went to sleep and when I woke up, it was finished! I always thought that 3D prints were weak, but I made this out of 80% solid infill. Its pretty much solid plastic, and man is it strong! I cant even flex these parts!
But what is it? Its a floating torch holder for our new plasma machine. The machine came with one that was broken and in imho it was a bad design anyways so why not make it the right way? This thing is awesome, it slides up and down on two rails with roller bearings fit inside the print, 2 springs and a bunch of metal bolts holding it all together! This is just too cool!
