1. An apparatus comprising:
two or more layers laminated together to define a substantially planar substrate;
one or more channels defined between two layers of the substrate, wherein each channel is defined by upper and lower walls and opposed side walls; and
a flexible conduit defined by a portion of the substrate encompassing an extent of at least one of the channels, wherein the flexible conduit is partially separated or separable from the remainder of the substrate, the flexible conduit comprising the portion of the substrate and the encompassed extent of the channel, and wherein the substrate comprises a cutout formed through the substrate and partially surrounding the portion of the substrate encompassing the extent of the channel or the substrate comprises a score line partially circumscribing the portion of the substrate encompassing the extent of the channel, wherein upon application of an external force to the portion of the substrate circumscribed by the score line, the substrate is configured to form a break through the substrate at the score line to enable the portion of the substrate to partially separate from the remainder of the substrate, and wherein the flexible conduit, when separated from the remainder of the substrate, is deflectable with respect to the planar substrate between an undeflected position in which the flexible conduit is substantially coplanar with the planar substrate and a deflected position in which a portion of the flexible conduit is not coplanar with the planar substrate.
