Pre-build log (was: Need diameter spec on 16AWG FEP supplied by DIYMOD)

Would anyone happen to know the outside diameter of this wire, including insulation: Premium FEP Silver Plated Copper Wire (Cu/Ag 16AWG)? I'm thinking about going sleeveless and am trying to plan my build, but can't seem to find that info anywhere.




TIA!

So I hunted down the spec for the 16awg FEP wire in question and am told it's 2.3mm in diameter, including the Teflon insulation (I'll firm that up once the cable gets here). Got 200 feet of it on its way, as well as a smaller amount of 22awg and 24awg at 40 and 80 feet, respectively. Want to see how well the smaller stuff works.

Now to develop the artwork for the cable combs for the 16awg size, keeping pitch in mind. Not sure if I'm going to use 0.08 steel or aluminum or possibly even 0.09 Delrin (black or white), but the artwork should work with all of them with adjustments that can be made relatively easy, if needed:



The taller version is sized @ 4.2mm pitch, which aligns with the motherboard plug, if one is needed there or close to it. The shorter version tightens up the group, for use further away from that plug. The outside grey areas are about as small as it gets given the resolution of the waterjets/lasers planned for use. The areas in grey will either be painted white, black, or perhaps some other color; haven't made up my mind at this stage.

That said, the same source artwork can be used for the other cables, just need to make sure conductor count and pitch are correct for the different sizes.

Acrylic/printed combs are out of the question because they’re just too darn fragile at these sizes. Sewing also wouldn't work well in this application because of the Teflon insulation.

Pinouts and full system schematic in work as well, tips on the way for my Pace just in case I do decide to rewire all of my fans.

Added version of comb with tightest spacing:



Rounded edges:



...and iterations thereof allotting for different connector sizes:

Wire, connectors, and pins arrived from MODDIY. Ordered 4/4, arrived today after sitting in customs for 4 days.

The FEP Teflon coated silver plated 16awg actually runs 2.0mm in diameter, insulation included:



Time to adjust the diameter of the holes and pitch in the cable combs for the cables I'll be making using it.

Latest update: been watching eBay (worldwide) for a proper crimping tool that can be used to crimp the "Dupont" pins for about 10 days or so now, but everything that's been offered has either been a real rust bucket, exhorbitantly priced, or questionable as to whether it was fully functional or not (e.g., HT-95, HT-100, or HT-208a). Had my eyes on a couple of HT-208a auctions, but they were priced higher than I really liked, and being shipped from the UK. Then, a few hours ago, a so-called "like new" 208a showed up for under $50, and I jumped on it. It does look pretty good for the most part, but I could see some surface rust of the moving parts and I'm pretty sure I'll have to disassemble it and give it a going over and lube job. Pretty happy though, and I should shortly have everything I need to finally start building, short of the parts I need for the lightbox, the cable combs, and a few other odds and ends.

Images of the 208a I bid on and won follow:
