Printrbot Simple LED clip

One of the problems with the Printrbot Simple is the poor visibility of the print area. This simple clip holds a bright white LED that illuminates the area. It is attached with the screws already present. The resistor in series with the LED depends on the powersource. A value of 270 Ohms should be O.K. in most cases. It is advisable to use a separate power source (6-12 Volts).
