Replacement for Prusa i3 MK3

Not much more to say than it works! The heater in my Prusa i3 MK3 stopped working for some reason, and rather than having to go through E3D or Prusa I was able to buy this replacement heater cartridge cheaply and locally so I didn't have to pay shipping. I took apart my extruder, heated up the heater block with a blow torch to soften the plastic, and was able to swap it out within an afternoon

Tight tolerances

The fibreglass sleeve is thicker than on the regular ones. Also the cylinder cartridge fits much more snug than the regular one, so, you have to be careful when pushing it through the heating block. 30 watt is a bit less than the 40 watt one but it was more stable and had extra juice left for the heating bed to heat up faster.

Worked exactly as expected

I had some concerns regarding the bending of the wires at the end of the cartridge bur I have used a screw driver as bending rod and I had no issues. Did not brake and made a nice curve allowing to push the protection (insulation) back close to the cartridge body.

Do as it's said.

Obviously, there is no need to tell you how awsome E3D is. This replacement work like a charm. The only bad point (commun to all ceramic cartridge) is that soldering are the weak spot and ther for prone to break.... beside that it is truly great
