The file 'Mini Arduino Laser Engraver 3D Printer Model' is (STL) file type, size is 275.3KB.
This is a frame for a mini laser engraver I made that is powered off an Arduino Uno. The instructions I followed can be found here http://www.instructables.com/id/Pocket-laser-engraver/
I used an 82mm x 64mm protoboard to mount the laser circuit and stepper drivers.
