Monoprice Select Mini v2 - Hotend LED Lights

thingiverse

I designed my own hotend lighting solution after none of the existing solutions worked for my MP Select Mini v2 printer. I positioned it directly behind the stock 30mm fan and attached two simple 5mm LEDs (warm white straw-hat style in my case) with convenient arms that point straight at the hotend. Both LEDs are connected in series to the 12v supply input via a single resistor, so they stay lit as long as the printer is on. The holder can be installed in under five minutes, but routing wires from the hotend to the base along the Bowden tube and down the main column takes some time. Alternatively, you could tap into the hotend fan wires, but that would mean the LEDs wouldn't work when the fan is off (e.g., during first layer printing). The lights can be glued in place or held with zip ties - I used both for extra security.
