Slidable rod rack system

A device comprising:

• a triangular prism-shaped support;
• and
• a slidable rack configured to slide back and forth along the triangular prism-shaped support, wherein the slidable rack comprises:
• a triangular base extending in a first direction that is substantially perpendicular to a surface of the structure and configured to slide back and forth along the triangular prism-shaped support;
• a member including a proximal end coupled to the triangular base and including a distal end, the member extending in a second direction that is perpendicular to the first direction, the second direction being substantially vertical and parallel to the surface;
• a first arm assembly comprising a plurality of first notches spaced along a length of the first arm assembly, wherein the first arm assembly is coupled to the member and extends in the first direction proximate to the triangular base, and the plurality of first notches open toward the triangular base;
• and
• a second arm assembly coupled to the distal end of the member, the second arm assembly including a plurality of second notches.
