This Github repository contains the Python macro component used during the DissolvPCB fabrication process. The macro enables users to design custom PCB assemblies using standard practices, then automatically convert the design into a 3D model ready to be printed. Also included are some PCB design examples that were used for the demonstration of the DissolvPCB fabrication process. Listed below are the prerequisites and instructions on how to utilize this tool. Detailed instructions on the entire DisssolvPCB fabrication process can be found under DissolvPCB Processs Details.
