A desktop machine that measures out a length of sticker sheet to be cut.

After laser cutting a sheet of Acrylic into all sorts of wonderful little pieces you are left with the problem of how to remove them from the machine. The answer lifting with a sticker sheet, this machine measures out 9.5 inch squares of sticker sheet for just this purpose.
Cut from 1/4" Acrylic. And uses a NEMA 23 size stepper motor and a roller salvaged from a surplus ink-jet printer.
