CNC Machine

This project was a final year project at the Faculty for Technical Sciences in Bitola, the scope was to design a CNC machine in 3D and develop bill of materials so that parts could be ordered online and it would be simple to build the machine.

The main use of this machine would be for wood cutting for the needs of a local woodworking business. Below I have uploaded the PDF of the whole project documented (I am working on translating it to English) and a link with the 3D model.
