Bowden Coupling for Metal E3D Heatsink

by mrwhitey

This is a M10 screw Heatsink Collet that you'll need if trying to fit a heatsink that had a PC4-M10 pneumatic connector to a Prusa MK2/3 extruder. Simple as that, don't need to buy that - just print it. Thread - M10 OD - 4 mm PTFE Note: I haven't tested how PETG responds to heat in that area so can't be held responsible for any melted PETG in your heatsink - but IMO heat doesn't go that far up to affect it.
