This is a concept 3 dof CNC machine using 3d printed linear bearings for the x and y axis. It's a modular design with a minimal amount of different parts, it also easily scales in size. I've assembled most of the first prototype and I'm in the process of redesigning most parts around the Z axis and parts for mounting the Y axis to the base. The Sketchup file contains all the plastic parts and groups the axis in components, I've also included a declaration of materials.
