Prusa Printer Lights Dual-LED Lamp

thingiverse

This set is a mount for the Prusa Printer for 2 LED Lamp panels with a power switch, that enables them to light up the print surface so we can see what we are printing! The parts to print are the bar mount bracket, the switch plate, 2x lamp arm. The lamp panels are simple 12v 48 SMD 40mm stick-on panels available as commodity parts on eBay or Amazon. The switch likewise is a round rocker switch also found on above sites. You will also need 2 M3x5 screws, and 2 M3x10 screws, a 1/4 or 1/2W 10 ohm resistor (so the lights don't get hot), and a couple of female crimp contacts for the switch, and a couple of crimp lugs for the power. I also used a few zip-ties as shown in the photo. Wire it up as shown in the schematic, then connect it to the Prusa 24V power supply. Note the polarity - if any of the LEDs are reversed it won't light up, so just reverse them. Make sure you turn off the printer first before connecting in to its power supply! Enjoy!
