Given the size of the machine having it hang on a wall isn't really that realistic IMO.I like this. Full support.
I like the idea of a wall-hanging crafting station. Would prefer if it gave more wire per bar, though...
I don't want to increase it anymore as wires sell for 1 silver each while bars only sell for 1.5 silver. Therefore you can make a huge profit rather quickly if it crafts more than 2 wire per bar. Though you can't buy copper so it's fine to have it craft a few per bar.
