The 2015 edition of the $38 DIY MCP design was updated to allow those with a 3d printer to produce a good quality and cheap MCP/Autopilot panel at home. This design, although simple looking, is one of my more complex designs. Creating substantial, more significant parts from many small parts was an exciting and lengthy process. The STL files are already FREE under downloads. This file is the CAD and STL files for those who want to take the design further or adjust certain parts.
