Design is done with FreeCAD (Plywood-7-Segment-Digital-Clock.FCStd). This file contains all the source models for 3D printing and the paths for CNC machining (you might have to re-create the paths for your CNC machine but you can use the FreeCAD file for this). My paths are generated to use with a GRBL based machine.
