3D Printer added

I assembled Tronxy 3D printer to make the expensive nuts I have been forced to buy from Texas. I think these are worth something and will probably begin selling the 3D model online. This nut was printed at a lower resolution than what the printer is capable of. So now for running the CNC it won’t be a week or two down when these inevitably wear out. Just 20 minutes to print another out of Nylon.
