I have a newer 3-v3 220x220x250 and tried to print sparkle pla and kept getting a nozzle plug, I went to change the nozzle to a .6 and the whole head turned and broke the thermistor and I can’t find the correct replacement. It’s 320C, 110 mm long and the end is 3mm dia. x 10 mm long, the wire end that goes on the extruder board locks to the board.
