I love the Prusa printers line. The only gripe that I have with it is that I have to use a lamp to see the filament when calibrating or when something goes wrong. I changed that. I made a frame that screws into the printer fan for a remote RGB light that connects to a rechargeable battery pack. I also wired the light with all of the other wires for the extruder. It is a light strip.
