So, John from Xardas (the 3D printer guy) did a couple gears for me on his 3D printer, and they turned out fantastic... I think, given how clean and simple it is, I will just get the gears printed. They come out similar to the machined gears, but it takes much less of my time, and won't add a lot of cost...
