Modular Tray System - Connects together - Different Sizes

Craft a basic modular tray setup that employs pins for interlocking. I designed this system for my 3D print business to organize parts in my toolbox and drawers. Ensure you produce an adequate number of connection pins for fastening the trays together. I suggest a maximum of two pins per side; exceeding this quantity might complicate disassembly or reconfiguration. Feel free to expand the system for larger dimensions if you desire.
