Modular Drawer Organizer – Gridless Interlocking System

A modular drawer organization system designed to work without a base grid.

Each module connects directly to the neighboring modules using integrated interlocking features. This keeps the organizer stable inside the drawer while avoiding the extra material, print time, and fixed layout of traditional grid-based systems.

The system is designed to be modular, reusable, and easy to customize. Boxes can be combined freely to match the size and shape of your drawer, while removable inserts allow the same box to serve different purposes over time.

Main Features:

• Gridless interlocking design
• Multiple modular box sizes
• Horizontal and vertical variants
• Removable specialized inserts
• Divider inserts
• Edge spacers for finishing layouts cleanly
• Split versions of selected large boxes for smaller printers
• Vase Mode box variants
• STEP files for customization
• Complete system STEP file

Included Inserts & Accessories
The system currently includes inserts and accessories for:

• USB drives
• SD / microSD cards
• 3D printer nozzles
• Hex keys
• Screwdriver bits
• M2 / M3 / M4 screws
• Rotary tools / Dremel-style tools
• Tape
• Wire
• Solder wire
• Makeup items
• General-purpose dividers
• Empty boxes for custom storage
  The specialized inserts are removable, allowing the same box to be reused for different purposes.
