Mini Desktop CNC

*** UPDATE 05.02.2019 ***
Step File added.

*** UPDATE 14.11.2018 ***
Corner Brackets added for 30x30 Extrusions.

This is another CNC machine inspired by many projects at Thingiverse. Plastic parts are designed as small as possible but powerful. The working area is directly proportional to the extrusion, rod and lead screw dimensions. Motors are Nema17. Arduino Uno + CNC Shield pairs were used as electronic equipment.

All extrusions are 20x20 but 30x30 corner brackets added to files.
