Designed from the ground up for clean, durable toolbox organization using the Gridfinity system.

This model was inspired by the excellent tool organization work of RobNordic, but every dimension, fitment, and feature in this design was created independently from scratch around my own tools and workflow.

Features:

• Standard 3U Gridfinity height
• Stackable Gridfinity-compatible lips
• Magnet-free design
• Designed for real-world toolbox use
• 1mm text height for title and labels

I specifically chose a no-magnet approach to keep printing simple, reduce hardware costs, and make the organizers easy to move, remix, and reprint.

This holder is designed for a collection of 1/4" socket attachments including:

• Long flexible extension
• 3.5" extension
• 2" extension
• Sliding T-rail attachment
• Wobble extension
• Bit driver attachment

These attachments came from a mix of different sets and brands over the years, and I wanted a clean dedicated organizer to keep them together and easy to access in the toolbox.

A little background on the project:

I’m still very early in my 3D modeling journey, and this collection has been a huge learning experience for me. All of these models were designed on an iPad using the free version of Shapr3D. Because of the limitations of the free version, I unfortunately can’t currently export STEP files; though I’m hoping to upgrade in the future as I continue building out this ecosystem.

Even so, I’ve put a lot of time into making these organizers practical, printable, and consistent across the collection.

Printing Notes:

• Prints great in PLA or PETG
• No supports or brim required
• 0.2 mm layer height recommended
• 3–4 walls recommended for durability
• Lightning 10% infill to save time and filament

If you print one, I’d love to see your setup and remixes. I’m building out a full matching tool organization ecosystem with consistent sizing and styling across the entire collection.
