3mm Single Braid Heatshrink Tubing (1/8")
1/8" (3mm) heatshrink, the size for single braided PSU wires. Each sleeved wire gets its own piece at each end, which is what stops the sleeve creeping back off the wire over time.
ModMyMods 3:1 heatshrink in black, blue, red and white, plus Phobya 3mm 3:1 in white at 30cm. 3:1 is the shrink ratio, down to a third of the starting diameter, which lets one size cover both the sleeved wire and the bare wire at the terminal.
A 24-pin cable is 24 wires and 48 ends. Buy more than you think, because running out at wire 20 means a color mismatch on the last four.
Sleeving to go under it is in 6mm PSU wire sleeving.
