Video Overview

Big thanks to Best Damn EDC (Taylor Martin) for putting together this deep dive into the modular MOD-GRID system by TinyToolShop. It’s a 3D printed take on Gridfinity built specifically for pocket tools instead of drawer bins, and it’s a genuinely clever way to organize a rotating EDC loadout. Taylor walks through the base grid, the swap-in tool mounts, a couple of community remixes, and how easy it is to reconfigure the whole layout in seconds. If you print your own gear, this one is worth the full watch.

Editor’s Insight

Taylor Martin has covered 3D printed EDC organizers before, but MOD-GRID is the first one that actually feels like it solves the problem instead of just riffing on Gridfinity for the sake of it. The base concept is simple: print a 4×12 grid of roughly 5.5mm cells, then snap in purpose-built brackets for whatever you’re carrying that day. Bit sleds, Swiss Army knife cradles, Knipex pliers holders, stash tin mounts — the brackets pop in and out on small plastic clips, so reconfiguring your loadout takes seconds instead of redesigning a whole tray. That’s the real innovation here versus a fixed, single-purpose organizer: it adapts as your gear rotates.

The community angle is what elevates this from “neat design” to “actual ecosystem.” Because MOD-GRID is open on MakerWorld, other designers have already started building on top of it. Darien’s magnet plate add-on lets you stick the grid to metal surfaces or hold small ferrous parts in place, and his ICON Flex Ratchet attachment clips the same grid system onto the lid of a Harbor Freight Icon ratchet set — instantly turning a static tool kit lid into extra EDC real estate. That’s exactly the kind of compounding value you get from an open, remixable file versus a closed commercial product. Taylor is candid about the current weak point too: the snap-in clips wear out with repeated swapping, especially in a more rigid PETG. His own testing found PLA+ actually held up better because of its slight flex, which is a useful data point if you’re printing your own set and want the mounts to survive more than a few reconfigurations.

On the sponsor side, Work Sharp’s new Madrone knife is a solid inclusion — a $180 integral aluminum-handle folder with an M390 clip point blade and the same swappable manual-to-auto pivot mechanism from their RMX line, now built at a new Oregon knife facility. It’s a meaningfully different shape from the RMX (thinner, clip point instead of drop point), and for a company best known for sharpeners, it’s a strong showing on the knife side. Big Idea Design’s mini bolt-action pen also makes a cameo as one of the parts that slots neatly into the MOD-GRID bit-extender mount — a nice example of how thoughtfully-sized EDC gear happens to double as a good fit for a DIY organizer.

Full disclosure from us here at the blog: we’re big believers in this kind of DIY EDC organization because we live it ourselves. We run a Bambu Lab P1S and a P2S side by side and print a ton of our own EDC gear — organizers, tool mounts, sheaths, you name it. Seeing a project like MOD-GRID come together is a great reminder of why we love this hobby: it’s community-designed, endlessly remixable, and costs basically nothing but filament and print time to try for yourself. If you’ve got a printer sitting idle, this is a genuinely useful weekend project.

Closing Remarks

MOD-GRID is a great example of how far community-driven 3D printed EDC gear has come, and it’s worth watching Taylor’s full video above to see every configuration he tries, including the Icon ratchet mod in action. If you print your own EDC organizer setup, or you’ve got a MOD-GRID variation of your own, drop a comment and let us know what worked for you. We’ll keep covering the best of the 3D printed EDC scene as it evolves, so stick around for more.
