My V6 HeatBreak is stuck in the Heatsink. It is nearly impossible to unscrew the HeatBreak out of the Heatsink because the HeatBreak and Heatsink is cylindrical in shape. There is no way to hold on to both of them to twist them apart. Is there a method or tip that would do the trick? Here I would like to suggest E3D to perhaps mill flat landings on both the HeatBreak and Heatsink so that there is a way to grip on to them to unscrew/twist them off each other.
