Reel Assembly with Multi-Part Core

A core kit for use in a reel for supporting wound flexible media, comprising:

• a first section forming a first partial cylinder between a first edge and a second edge, the first edge including a first lateral protrusion extending therefrom, the first lateral protrusion having a detent;
• and
• a second section forming a second partial cylinder and couplable to the first section, the second section including a first receiver configured to receive the first lateral protrusion and engage the detent via a retention structure to at least in part couple the first section to the second section, and
• wherein at least one of the first lateral protrusion and the first receiver is elastically deformable to allow the first lateral protrusion to slide in an engagement direction past the retention structure, and then release from at least part of an elastic deformation after the protrusion passes the retention structure to engage the retention structure to inhibit disengagement of the first section from the second section;
• and
• wherein the first section and the second section are each configured to be coupled to a first flange and a second flange.
