A simple light bar that rests on the top of the z end stops, I used some cheap Christmas led stick on strips and a buck converter to power from the power supply! It wont fit on a mk3 bed sadly, i had to print it on my anycubic chiron!!
Ok update, if you have the mmu2s, the top of the extruder hits it!! ill have to work on that!
