This is version 2 of my nozzle light. It uses two 12V LED strip segments wired in series to the 24V supply via a 100ma fuse. The front and rear LEDs light up the area under the nozzle enabling you to clearly see the layers being printed.The rear strip holders are slim so not to catch on the rear Z axis guides. The holders are designed to clip onto the nozzle carriage so as not to require any permanent modifications. Parts 2 x LED Segmnets. I cut 2 from a roll on e-Bay." Super Bright White LED Strip Light Waterproof 5m 12V 5050 SMD Flexible 300LED" In-line fuse holder. Hook-up Wire Remember to wire the 2 LEDs in series NOT parallel as the supply is 24V and the LEDs are 12.
