Thanks for letting me know little known fact you can dye nylon with cool aid

That's a new one.  How do you do that?

Couple of things about that:
1.  This carrier is made of some type of Nylon, so I'm not sure how well paint will stick to it.
2.  Paint will probably affect the smoothness of the cable.  Right now, the links move very smooth, but the tolerances are minimal to prevent sagging, so adding a layer of paint may not be the best thing to do with this cable, unless it's applied only on the external, non-contact surfaces.  If paint gets between the links, it won't work well.

I have about 30ft of this stuff, so 20" is not a set size, it just so happens that is all that is needed for a SD2/3/4 build, but if you need more, or less, it's doable, just let me know the size you need.

MicroTrack cable chains come in a variety of sizes, and this particular cable is model KR37 0130.15. 

Here are the specifications:

• Inside 15mm High x 9mm wide.

• Pitch (distance between pivot point of each link): 13mm

• Bend Radius:  37mm

• Total length of all links (not including the anchor ends): 20mm

• Total number of links: 40

• Includes 2 anchor ends.

The price is $20 for the set + $5 shipping via USPS Flat Rate Box Priority Mail
