1. A system for holding a roll of film, wherein the roll comprises a core with film wound around the core and the core has an inner surface, the system comprising:
a rod having an outer diameter that is smaller than an inner diameter of the core;
a proximal wing located on the rod and configured to rotate about the rod, the proximal wing including:
contact surfaces configured to contact diametrically-opposed locations on a proximal side of the inner surface of the core, and
non-contact surfaces that span between the contact surfaces of the proximal wing, wherein the non-contact surfaces of the proximal wing are configured to not contact the core if the core has a cylindrical shape; and
a distal wing located on the rod and configured to rotate about the rod, the distal wing including:
contact surfaces configured to contact diametrically-opposed locations on a distal side of the inner surface of the core, and
non-contact surfaces that span between the contact surfaces of the distal wing, wherein the non-contact surfaces of the distal wing are configured to not contact the core if the core has a cylindrical shape;
wherein the distal wing is capable of rotating around the rod independently of the proximal wing; and
wherein at least one of the contact surfaces of the proximal wing includes an engagement device configured to engage the inner surface of the core and to deter rotation of the core with respect to the at least one of the contact surfaces of the proximal wing.
