Interchangeable and interconnectable tool organizing device

A modular custom mechanic's tool accessory to hold a plurality of mechanic's tools, the custom tool accessory comprising modular mechanic's tool holders that are interconnectable to cooperatively hold a plurality of mechanic's tools, each mechanic's tool holder comprising:

• (a) a body;
• (b) a plurality of tongues disposed at a first side of the body;
• (c) a plurality of tongue receiving grooves disposed at a second side of the body opposite from the first side of the body;
• (d) wherein the plurality of tongues on the first side of the body engageable in locking relationship with grooves of a first adjacent holder for mechanic's tools and the tongue receiving grooves disposed on the second side of the body engageable in locking relationship with the tongues of a second adjacent holder for mechanic's tools;
• (e) a mechanic's tool holding portion disposed on the body to engage and hold the mechanic's tool, the mechanic's tool holding portion comprising:
• a first planar base section;
• a first upright wall having an inclined inner surface disposed at an angle projecting upward and laterally outward from a side of the first base section and having an upright outer surface opposite to the inner surface;
• and
• a second upright wall spaced from and extending along the first wall, the second wall having an inclined inner surface disposed at an angle projecting upward and laterally outward from the opposite side of the base section from the location of the first wall and having an upright outer surface opposite the inner surface;
• (f) a missing mechanic's tool color indicator:
• disposed at the planar base section of the mechanic's tool holding portion, and of a color different from the color of the remainder of the mechanic's tool holding portion and the body, the color of the missing mechanic's tool indicator is unrelated to the color of the mechanic's tool and
• the color of the missing mechanic's tool indicator is of the same color as that of a missing mechanic's tool indicator of another mechanic's tool holder to which the mechanic's tool holder is interconnected;
• (g) wherein the missing mechanic's tool indicator is visibly blocked from sight by the mechanic's tool when the mechanic's tool is engaged and held by the mechanic's tool holding portion and is visible to sight when the mechanic's tool is removed from the mechanic's tool holding portion;
• (h) wherein the plurality of tongues extend longitudinally along the height of the outer surface of the first wall and projecting outwardly away from the outer surface of the first wall;
• and
• (i) wherein the plurality of tongue receiving grooves are recessed into the upright outer surface of the second wall to extend along the height of the outer surface of the second wall.
