This package is a compilation of months of research, testing, and developing. The end result is a package that coaches the user through how to use their 3D printer to aid in electrochemical machining of a stock-sized steel tube for the purpose of creating a 9x19mm barrel. CAD, directions, tutorial, and troubleshooting tips are included. This is literally the IKEA of barrel making, all for 100 bucks in supplies.
