I'm trying to replace my hotend with the E3D Hemera direct kit. I got to the final step of hot-tightening the hot side and managed to snap my heatbreak. The part that screws into the heat-sink is stuck, though I was able to remove it from the heater block section.
Below is a picture of the heatbreak. The red square shows what it in the heat-sink. It's mostly thread (with thermal compound) but a bit of the unthreaded metal is sticking out (above the disk shown).
I've tried removing it with a jeweler's drill (which is how I removed the heater block portion, but I cannot get a good grip on the long threaded piece. I've also tried pliers and rounded needle-nose pliers. Neither worked. I couldn't find my regular needle-nose and will go to the store to try that. Are there other options to break this free or am I stuck with buying a replacement heat-sink? I already ordered a replacement, but it'd be nice to have a backup in case something else goes awry (as has been the case with this modification; this is snafu number 4).
