12V 40W 1/4-in (6.35mm) Ceramic Cartridge Heater for 3D Printer MK10 Extruder/Hotend

And presumably the Wanhao Duplicator as well.Took like 5 minutes to install, fits great. Appears to be heating reliably, though I've only had it in for like 20 minutes. Actually seems like a slightly *better* fit than the stock one, in that it is the same length as the heater block, rather than being a few mms longer.To install, I used: * A crimper * A heat gun * Two butt splices * A pair of angle shears (sisors or blade would work fine) * the hex wrench included with the Maker Select * Small pliersI heated the extruder to 210, and unscrewed the screw on the bottom of the heater block with the wrench, and then removed the core from the block with the pliers (no resistance once it's hot and the screw is out). I put the new one in place while the block was still hot, put back the screw and turned the printer off. I clipped the cables to length (they're excessively long for this purpose!) And clipped just past the fat part of the stock butt splice, wanted to keep as much length as possible. I trimmed off the remainder of the butt splice from shielding using the shears, and stripped off 5mm to expose the wire on both sides using the crimper. Then I just attached the two new butt splices to the heater side using the crimper, and then to the printer side (A bit fiddly, getting that close to the gantry, but it's doable). Then I used the heat gun on the splices to shrink the shielding down, and turned on the printer to test it out, and it was working.I might recommend using smaller butt splices than I did, but they worked anyway!

As an engineer who works on similar products the overall constructions looks good therefore I'll give them 4 stars. However the wires are 21.27 CM too short to be able to be installed in the Flashforge Creator Pro which unfortunately is what I need them for. The Flashforge Creator Pro heater cartridge has leads that are 121.28 CM from the back of the shell to the end of the wire.

The heater cartridge itself is the perfect diameter for the Maker Select. I just snipped the wire and used Wago connectors to connect them to the wire that runs to the control box. It feels sturdier than the original heater cartridge. I highly recommend.

Used this to replace the heater block in my Wanhao i3. Perfect fit, easy to install. The wires are very long so you'll have to cut them to size and connect them.

Product works perfectly and the cables are robust! I purchased this to replace a broken part on my Monoprice v2 3D printer, and it does the job! It was a bit of a squeeze to get in the assembly (the housing on my printer is 6.3mm), but it works like a dream. Very sturdy construction and a great price.

Great replacement with long wires. this heater feels like the original that my printer came with.

Seems well made, good wire covering and more near the hot end. Better than the stock on my Monoprice Maker Select V2.

Just what I needed, working well on my Monoprice Maker Select v2.
