About us

At Kos Design, everything revolves around smart storage solutions that make a difference on the job. We specialize in designing and producing high-quality, 3D-printed inserts that fit seamlessly into toolboxes from brands such as Milwaukee, Makita, Festool, and DeWalt. Our products were developed with one goal in mind: to help professionals and DIY enthusiasts better organize their workspace and work more efficiently.

Kos Design was founded by two construction professionals who repeatedly encountered the same problem in their daily work: the lack of efficient, secure storage solutions for their tools and batteries. When they realized that these solutions simply did not exist, they decided to take matters into their own hands. This need inspired the idea for perfectly fitting inserts, specially designed for the tools they used themselves every day.

From battery chargers to multi-tools, each insert is designed with the utmost precision to provide maximum protection and visibility. Thanks to the robust materials and thoughtful layout, tools remain securely stored even under the toughest conditions. This keeps everything within easy reach, exactly where and when you need it.

Our production takes place entirely in the Netherlands, with a focus on quality, dimensions, and durability. By using 3D printing technology, we can respond flexibly to our customers' needs and guarantee a perfect fit in any Packout system or other modular storage system.

Whether you are working on a construction site, in a workshop, or at home on your own projects, Kos Design inserts help you get the most out of your tools and storage box.
