A man in possession of a good set of drawers is likely seeking an effective organization system. After purchasing a Bisley chest of drawers on wheels, which doubles as a pull-out seat, the author faced drawer chaos—tangled cables, misplaced snacks, and other clutter. Frustrated by off-the-shelf organizers that didn’t fit his needs, he discovered foamcore, a versatile material made from two sheets of paper with hard foam in between. This simple yet sturdy material became the basis for creating custom drawer organizers.
To build foamcore drawer organizers, you’ll need a sharp knife, a hard edge like a carpenter’s square, a cutting mat, craft glue, and small pins. The process involves determining the shapes required based on the desired box dimensions (width, depth, height) and the thickness of the foamcore board. The author developed an online calculator to simplify measurements, especially since the 5mm thickness impacts geometry and fitment. By calculating panel sizes for sides, bases, and other components, you can create open boxes that are easy to remove from drawers. For example, a box with dimensions 85mm (width) x 128mm (depth) x 45mm (height) requires specific measurements to ensure proper assembly.
One of the challenges is ensuring precise fitment, as even a millimeter difference can cause issues. The author emphasizes testing the fit with offcuts before final assembly. Additionally, foamcore organizers can be customized beyond basic open boxes—such as adding risers for easy access to items, creating stackable containers by shaving sides slightly, or incorporating dividers. These variations make foamcore organizers versatile and adaptable to different drawer storage needs.
For those interested in tech and startups, this method offers a practical solution to everyday organization problems. By repurposing inexpensive materials like foamcore, individuals can create tailored drawer systems without relying on store-bought products that may not fit their space or lifestyle. The calculator tool also highlights the potential for tech-driven solutions to simplify even the most mundane tasks, making it a compelling example of how innovation can enhance productivity and efficiency in everyday life.
