Hey man!
3ft should be plenty for the length that you want. 4 inch of coil and 8 inch of straight is no worries.
Teleios and Techflex are recommened for double sleeved coils. I would go for Techflex or Paracord as the base then Techflex on top so you can see the base layer through it.
Anything else I can help with, let me know!
thanks man!
So this is okay: Teleios dark gray as base with Techflex black on top?
i will add this in the "Anything Else? List any lengths of coil etc :" box:
Connector #1*:Mini USB (male) for the keyboard
Connector #2*:Micro USB (male) for the tablet
Coiled 4 inches and straight section 8 inches
Coiled have micro usb and straight have mini usb
so you will understand what i mean
