Bring a reusable spool back to the bench

Teach the refill demo (refill demo for the workshop), load training (teach newcomers AMS loading), and label via label inventory in Filament Manager. Materials board: filament materials reference.

More angles on the same empty spool: AMS studio shop · stocking shop · reuse shop · field-guide shop · short buy path

Club tip: bring one test empty to the shared toolkit, label it “club standard,” then reorder matching spools so everyone loads the same shape.
