A cartridge assembly (10) includes a cartridge (12) and a cartridge retainer (14). The cartridge (12) includes a reel (22) having a rotational axis (46) and a flange (48, 50). The cartridge (12) also includes a cartridge housing (16) that rotatably secures the reel (22). The cartridge housing includes one or more interior surfaces (19, 21). The reel (22) is adapted to tilt relative to the cartridge housing (16). The cartridge housing (16) includes a plurality of ribs (30) each having a chamfer (72). The ribs (30) can be disposed on an upper housing section (18) and/or a lower housing section (20) of the cartridge housing (16). The reel (22) has a contact tilt angle θ 1 relative to the interior surface (19, 21), and at least one of the chamfers (72) has a chamfer angle θ 2 relative to the interior surface (19, 21) that is substantially similar to the contact tilt angle θ 1 . The flange (48, 50) contacts the chamfer (72) so that the flange (48, 50) is substantially parallel with the chamfer (72). The cartridge (12) can also include a positioner rib (66) for laterally positioning the reel (22). Further, a flange edge (56, 60) of the flange (48, 50) does not contact the cartridge housing (16) when the reel (22) tilts. The cartridge assembly (10) includes a reel positioner (36) that biases the reel (22) of the cartridge (12) toward the upper housing section (18) of the cartridge housing (16) while the cartridge (12) is retained within the cartridge retainer (14).
