About this 3D model

This holder can be used to organize and secure aquarium air lines, hole in center can be used to mount it to a flat surface. Some brands of hose fit fine, but others are just thick enough that you may want to push the hose through it lengthwise than trying to snap it down from the top. _UPDATE 8/15/14:_ Wall thickness increased to prevent breaking while pushing hose through. Should be much stronger now.
