Hi everyone! Ive been trying to fix a persistent printing problem with my Rep 2 and i have replaced most of the parts on the extruder assembly except for this piece and since i finally figured out that there are some pretty wild temperature variations happening so the heater seems to be the root cause (hopefully). Unfortunately, this particular part has been VERY difficult to find for some reason and the ones i have found don't look like the one that is currently installed so i am not sure if they will work. If any of you guys know where i can get a compatible heater cartridge it would be greatly appreciated.
