Gridfinity Socket Adapter & Extension Holders

Boost Me ⭐ Enjoy it? Give this model a BOOST — boosts help more makers find it and keep new toolholder designs coming! A better way to store extensions, adapters, and wobble joints in your Gridfinity setup. These holders grip each tool by the drive side , not the outer diameter — which means they work with any brand, any style, and any shape (thin walls, thick walls, stepped bodies, impact, chrome, etc.).

No more adapters that don’t fit because of weird outer diameters. If it has a ¼”, ⅜”, or ½” square drive , it fits.

🧩 Highlights • Works with all extensions, adapters, universals, and reducers • Drive-side capture means no OD measurement required • Holds tools upright and organized in any Gridfinity layout • Mix and match across plate sizes and colors • Perfect for mechanics, hobbyists, tool carts, shop drawers, and mobile kits

⚙️ Print Settings • Layer Height: 0.2 mm • Infill: 15–25% • Supports: None • Material: PLA, PETG, or ABS

💡 Tips: • These work best printed solid at the top layers to prevent flex. • For heavy extensions, bump infill to ~25–35%. • If you want a tighter or looser fit, scale X/Y by ±2% .

🧰 Why This Works Better Unlike OD-based holders, these don’t care whether your extensions have: • Impact housings • Chrome shafts • Shoulders or grooves • Knurling • Tapered bodies

If it clips into a ratchet, it clips into this module.
