Snap-together structure

A snap-together structure, comprising:

• a plurality of elongated wall members each comprising a first pair of spaced apart opposite side walls integrally connected by a second pair of spaced apart opposite side walls, said first pair of said side walls having straight opposite ends extending between said second pair of said side walls, each of said wall members including a pair of elongated locking channels respectively extending longitudinally on said second pair of said side walls, said wall members being positioned laterally against each other, so that locking channels of abutting wall members are positioned parallel to and facing each other;
• a plurality of end caps substantially matching said wall members in cross sectional outer dimensions, each of said end caps having a pair of end cap locking channels extending longitudinally thereon, and an end channel on one end extending communicably between said end cap locking channels, each of said end caps including a plug portion extending from an opposite end, said plug portion having smaller cross sectional outer dimensions, said plug portion sliding between said first pair and said second pair of said side walls of one of said wall members, so that said end cap locking channels are aligned with said locking channels on said one of said wall members, end channels of adjacent end caps are in communication and alignment with each other;
• and
• a plurality of elongated connecting members positioned longitudinally in said locking channels of said abutting wall members, each of said connecting members is sized to securely engage the locking channels so as to connect said abutting wall members together, further ones of said connecting members also positioned across said end channels of said end caps.
