Modular grid system

A modular grid system comprising a first modular grid and a second modular grid, wherein:

• a. the first modular grid and the second modular grid are coupled via a plurality of interlocking tabs and receptacles;
• b. the first modular grid and the second modular grid are oriented in the same direction;
• and
• c. each modular grid comprises:
• i. an outer frame;
• ii. an outer partial ring positioned inside of and coupled to the outer frame, wherein the outer partial ring forms an arc of greater than 180 degrees but less than 360 degrees;
• and
• iii. at least one inner partial ring positioned inside of and coupled to the outer partial ring via at least one securable connection, wherein the at least one inner partial ring forms an arc of greater than 180 degrees but less than 360 degrees.

A method of forming a modular grid system comprising the steps of:

• a. providing a first modular grid and a second modular grid, wherein each modular grid comprises:
• i. an outer frame;
• ii. an outer partial ring positioned inside of and coupled to the outer frame, wherein the outer partial ring forms an arc of greater than 180 degrees but less than 360 degrees;
• and
• iii. at least one inner partial ring positioned inside of and coupled to the outer partial ring via at least one securable connection, wherein the at least one inner partial ring forms an arc of greater than 180 degrees but less than 360 degrees;
• b. providing a first aperture-forming device and a second aperture-forming device;
• c. coupling the first modular grid to the second modular grid;
• d. coupling the first aperture-forming device to the first modular grid;
• and
• e. coupling the second aperture-forming device to the second modular grid.
