I switched from the stock hot end to a E3D V6 hot end. The clip for the heat sink collet is very tiny and I almost lost it a couple of times. This one is easier to handle. It is a remix of the one from deckingman. The front is beveled so that it slides under the collet lip easier and the slot to slide the clip into position is widened slightly.
