I made one from a mini-flashlight, a metal pen tip and some hot glue. Part of the flashlight twists off so that you can just insert a piece of coffee filter and when you twist the cap back on the filter is made taut. The other end was partially punched out and the metal pen piece inserted to make the butane dispense. Hot glue was added around the cap to make it air tight at that end.
I just tried it with a joint paper and now everything smells like resin. Can't wait to use this paper to roll (not until tomorrow.)
