Solder, use cable blocks or crimp to add extra cable. For the heater cartridge you need to use 24AWG. For the thermistor you can use 28AWG.

Order a longer set locally. The heater cartridge is 24V, 40W, 6*20mm. The thermistor is a 100k NTC thermistor. They are both very common and cheap parts (little over a dollar each), you should be able to find them on sites like Amazon, eBay and Aliexpress:

Or get in touch with us by completing this form.
We have received the short cables. Can we limit the max z axis height in the software? Or do we need to keep this in mind when printing individual parts?
In Cura you can set a new Z-height that will warn you if a part your printing is too big, until you receive the correct length cable.
The thermistor has the wrong connector as well. It should be a JST (as shown in the wiring stage) rather than the female jumper connector (as shown above). Albeit, since I have a stash of JSTs and had to splice the extra 20 cm anyways … well, it wasn’t all that big a deal.
A decent network patch lead is 24AWG (most are clearly marked on the outer insulation but do check as cheaper ones can be made out of thinner stuff). They make a great source for the extra cable needed if anyone is trying to find some suitable cable in a hurry.
I used that hack a long time ago on my prusa and it still works

These cables (2 meter is the next size) do not appear to be available in the USA which means shipping for purchased replacements will be two weeks or more. At this time my assembly has come to a sudden halt. I have already asked for the correct part to be sent but am getting no respone. Is there another viable alternative ?

The fan mount assembly pops off the heat sink like shown.

If I knew that I would have to completely assemble it, I would not have backed it. I have arthritis in my hands and cannot hold the Allen wrench.
agree with Howard
thermistor needs heat compound to make temp more stable and accurate.
