This is my take on the Modular Organizer System. I wanted something larger than I saw in most designs so I decided to create my own.

This system consists of 8 total interconnected modules and 8 drawers (3 bottom, 3 middle, 2 top).

I bought small antique brass knobs online that are designed for Jewelry boxes and they really work out well with the design. https://www.amazon.com/dp/B01N8UCKYS/ref=cm_sw_em_r_mt_dp_21R1VPSXFMER74EGWSYK?_encoding=UTF8&psc=1

Each module measures about 96mm (Length) x 96mm (Width) x 127mm (Deep).

I used small M4x8 bolts to connect the knobs. The Modules and Drawers fit together very snug and the drawers slide in and out very easily.
