This is a flatbed pen plotter made out of some old printer parts, some 3d printed pieces and a servo motor.
It is controlled by means of an arduino with a cnc shield and it is capable of printing A3 size paper, PCBs, notebook covers...
Find a gif (soon) of it working down below.
Note: This is uploaded just to use as reference. I will answer some questions in the comments, but I am not providing any information on the printer models used or specific parts (mainly becouse i don't have that information)
