Magnetic Front Tool Organizer for Mini Tool Carts

A magnetic tool organizer designed to hold pencils, screwdrivers, pliers, and small hand tools on the front of mini tool carts. Unlike clip-on or tray-style accessories, this organizer mounts magnetically to the front of the toolbox and rests on the cart surface for added stability—and it's sized so the lid can fully close with the organizer installed. Many mini toolbox accessories block the lid—this one doesn't.

Compatibility

Works with:

• Harbor Freight General Mini Tool Cart
• Kobalt Mini Tool Cart
• Other similar mini toolboxes (any color)

This design is intended to work in conjunction with the Harbor Freight Mini Toolbox Cart by BB's 3D Garage.

Important Note on Magnet Strength & Placement

Magnet strength and placement really matter.

This holder relies on magnetic force combined with the physical support of resting on the cart. Using the correct magnet size and ensuring the magnets are fully seated and properly aligned is critical for real-world use.

• Weak magnets will not hold the organizer securely
• Poorly seated or misaligned magnets will significantly reduce holding strength
• For functional use (not display), high-strength 8 × 3 mm magnets are strongly recommended

Magnets are designed to be press-fit. For best results and long-term reliability, add a small drop of CA glue during installation.

If magnet strength or placement is compromised, this should be treated as a light-duty or display-only accessory.
