The use of these connectors is entirely optional! This is how I like to rig my printers and it's
entirely okay to not do this. The pre-assembled printers from SeeMeCNC don't include these
connectors, so don't feel obligated to use them. Now that being said, having a quick-disconnect hot end
is just cool. :)
The JST connectors can be purchased from Hansen Hobbies as well – just make sure you order
the right pins! Read the description pages carefully.
The JST connectors can be found here:

If you don't already have a crimping tool, the one shown above will do the job, but the best
choice would be a ratcheting crimp tool like this one from Pololu:
That's the tool that I use on my projects. It's reasonably priced at $34.95.
There was a great discussion on the SeeMeCNC forums recently on how to properly use this
kind of crimping tool. I recommend you check it out if you haven't used this kind of tool before.
