Simple Led Addon for Prusa i3 MK2s

thingiverse

I needed a non-invasive, easy-to-use LED add-on for my Prusa i3 MK2s. I ended up with this solution. It's essentially a support for a short 5 cm long 12 v LED strip with two hooks because regular glue won't withstand heat. You can easily secure it by using the two bottom fan screws (you might want to swap them out for 20mm long screws instead of the standard 18mm). DOUBLE CHECK that there's no issue and the extruder body can move all the way to the left. Make sure to pass the wire correctly along with the thermistor and nozzle heater. ELECTRONICS: I ran a couple of wires soldered directly into the RAMBO board, coming straight from the PSU. This LED strip absorbs less than 5 W of power. Note: New Prusa printers don't use a 12 V power supply.
