Nozzle light Prusa MK3S+

prusaprinters

The nozzle of the MK3S lives in the shadows. Even the brightest light from above doesn't light up the space underneath the extruder. Having a light beside the nozzle gives you a better sight of even the first layer.This one is for the original Prusa configuration of the MK3S+ (perhaps also the older models, but I don't own any of them).It is mounted underneath the noctua 40x40 hotend fan with the original screws. Depending on the condition of the holes in the extruder (no nuts are inserted for these screws), 2 mm longer screws might also be necessary.The rear end is raised so as not to collide with the heating bed connection, when calibrating or printing large parts. There is also a second part (sup) which can be used to fill the gap between the extruderend the optional mounting hole nearby the cable routing.For mounting instruction see the pictures - it's easy.Additional parts you need to make it work:LED Strip - cut off a 5 cm piece - depending on your Power supply 24 or 12V , not more then 8 mm width. A slot in the front and the cable routing hold it even if the double-sided 3M tape fails.2-wire cable - AWG22 is fine - soldered to the LED strip and routed through the extruder harness to the power connectors in the einsy housingM3 x 18 mm screw from the spare parts packOptional: Switch to be able to operate the light separately from the printer. You maybe interested in this one.The pictures show my first prototype which was very simple, unstable, to high mounted, … in simple words a nice try, but nothing more. You see, that I had even to modify the fan to fit into.The provided parts are the last evolution, which I used before smithed to another nozzle fan shroud and have to develop the next one here.Unfortunately, I forgot to take pictures of it in live operation. But be promised it it much better than the pictures.I recommend PETG, because it is near to the hotend and even the LEDs heat it up enough to make PLA weak.The 3mf file is ready to print and as you see has even some painted support underneath only the really necessary partsUpdate 06.2023Added STEP files on request
