Printrbot Simple LED clip

thingiverse

To get a clearer view of what's printing, you might struggle with the Printrbot Simple due to its print area being somewhat obscured. But no worries, one clever way to address this issue is by adding a bright white LED light that shines directly onto the printing surface. Simply snap this simple clip into place using the existing screws and voila! The resistor's value, which depends on your power source, will likely be around 270 Ohms - although you might need to check your specific situation for verification. It is highly recommended to use a separate power supply with an output of between 6-12 volts for the LED.
