Key Takeaways

• MODGrid adapts the open‑source Gridfinity modular base‑plate system for pocket‑sized Everyday Carry (EDC).
• The system uses a 42 mm × 42 mm grid (standard Gridfinity module) that snaps 3‑D‑printed accessories in place without tools.
• Printed in PLA or PETG (≈ 1.75 mm filament) with a 0.2 mm layer height, a full MODGrid kit weighs ≈ 45 g and fits inside a standard 2 × 3 in pouch.
• Compared with traditional EDC pouches, MODGrid offers up to 60 % more configurability and eliminates the need for proprietary inserts.
• Files are freely available on GitHub and can be customized with the Gridfinity Layout Tool or Gridfinity Generator.

MODGrid: Bringing Gridfinity Modular Organization Into Your Pocket

What Is Gridfinity?

Gridfinity is an open‑source, 3‑D‑printed modular platform originally designed for workshop storage. Each module measures 42 mm × 42 mm (the “grid unit”) and features a M3‑threaded “click‑lock” that secures accessories such as bins, tool holders, or scissor racks. The system’s popularity stems from three core assets:

The ecosystem includes the Gridfinity Layout Tool (web‑based layout planner), Gridfinity Generator (parametric STL creator), and a community‑driven wiki that documents dozens of accessory designs.

Everyday Carry (EDC) – A Brief Primer

EDC, short for Everyday Carry, is a subculture centered on keeping a curated set of tools on one’s person for emergencies, productivity, or simply habit. Typical items include:

• Key‑chain carabiners (≈ 30 g)
• Miniature flashlights (up to 100 lumens, 40 g)
• Multitools (e.g., 5‑in‑1 pocket knives, 55 g)
• Paracord bracelets (≈ 15 g)

According to EverydayCarry.com, the global EDC market reached USD 2.3 billion in 2023, driven by a surge in “self‑reliance” narratives and the proliferation of tactical‑grade accessories.

MODGrid: Gridfinity Adapted for Pocket Use

TinyToolShop (YouTube channel “3DEDC”) introduced MODGrid—a miniature Gridfinity board that fits inside a standard EDC pouch. The concept is simple: a 2‑row × 3‑column grid (total 6 modules) printed as a single base plate. Each module can host a bespoke accessory, such as:

• Bit holder for 1.5 mm screwdriver bits (holds up to 12 bits)
• Mini Knipex pliers mount (holds 2 mm‑wide pliers)
• Ratchet/torque‑wrench insert (0‑10 Nm range)
• Fold‑out blade carrier (up to 3 mm thick)

All accessories click in place via the same M3 click‑lock, allowing users to re‑configure the layout in seconds. Because the files are parametric, designers can scale the grid to 38 mm for tighter pockets or 45 mm for larger pouches.
