Sure. Mod/Smart - High Density Kobra | Page 1 | Sort By: Product Title A-Z - FrozenCPU.com. Scroll down the page a bit to find the individual sizes sold per foot instead of in a kit. I bought a few feet each of 1/4", 3/8", 1/2", 3/4", and 1". The only one I didn't use any of was the 1" (it was a contest between 3/4" and 1" for the big sleeve in the center of the photo I posted earlier; the 3/4" barely won).
I had to use some 3-1 heat shrink sleeving I had leftover from the previous case I modded; 4-1 would have been better but I couldn't find it.
I cut the sleeving with an old Telco knife I keep knocking about for just that purpose. I heat the blade up in the flame of my gas range until it's just hot enough to more melt than cut its way through the sleeving. That automagically seals the end if the sleeve so it won't unravel but it still can be expanded by opening a pair of pliers or scissors inside the end or by forcing it over a tapered object, such as a pen with a tapered end. Once expanded, it will return to its original size and still won't unravel.
