Stopped at 16 rolls, because I don't buy my vinyl in rolls often, but this seems to work great, spins freely with no bearings.
For the build you need: the base bottom, the base top, and for each 4-roll module you need 2-plates, 2- plate connectors, and 2 connector clips. I printed with brim and for some a raft, only because on occasion I have adhesion issues with this printer, not sure you need them.
