I finally tracked down some 3in rolls over here. I could only persuade the shop to sell me two - otherwise they wanted me to buy a whole box (I might go back for them later). Anyway, here is my effort so far.
I addapted a box that originally held a block of note paper to hold my roll. Two holes drilled in it, and an old plastic knitting needle did the trick (I cut it to length).
A couple of large hair grips are keeping things under control at the other trimmed end.

I think you could drill a plastic holder too if you had the right drill bit
