This hotend assembly is almost identical to my original Ender 3 Pro parts. A small (a little uncomfortable) difference is the exact size of the tapered thread that the Bowden tube coupling attaches to. The coupling must be twisted further than the original. This wouldn't be a problem for most, but in my case I made a "Hot Fix" mod. (Google it). And that doesn't work either. Also some other small differences. The Phillips head screw on the original thermometer has been replaced with a flat head hex key. The coating on the heating block is yellowish. Assembled it is approx. 1 mm longer. But it fits and prints exactly the same. It even has connectors on the fan parts and thermometer wires that match the motherboard.
