An apparatus may include a substrate material. The substrate material may lay substantially planar along a first axis. The apparatus may also include a plurality of punch-outs consisting of the substrate material and fastened to the substrate material. Each punch-out may be to be removed from the substrate material with an application of force upon each punch-out to create an open space in the substrate material. The apparatus may also include a first plurality of linear joints in the substrate material to allow the substrate material to be folded into a box form including at least five sides. The box form includes an inside portion. |
