This model can hold a variety of items. Examples of those items include skateboards, bags, keys, etc. This is very useful for storing multiple items in the same place or area. I have changed the model so it has screw holes in the corner and also removed the poles at the top that acted as screw holes but they weren't as efficient. The 3d observer thing isn't the up-to-date model. The pictures are up-to-date.
