E3D Toolchanger Pitlane with captive nuts

Throughout the build of the E3D Toolchanger I noticed a significant number of parts that rely on tapping into plastic printed parts, in my experience this is a great method when using M5 and above sized threads, but is not very reliable when dealing with M3 and below as they strip easily. To avoid this I like to use the captive nut technique, in this case you will need a pair of M3 nuts (nyloc if you are feeling super fruity).

I was on a bit of a roll with adding captive nuts to various Toolchanger components so I thought I would do this one while I am at it.
