Expandable Screw Box Holder

This is a 3D-printed, wall-mountable organizer designed to store standard hardware store boxes of screws and nails. The design keeps labels visible and provides quick, tool-free access to contents—perfect for keeping your workspace tidy and efficient. (Some boxes can be slightly different, I tested with the boxes I have and it worked great.) The system is modular, using precision dovetail joints that let each unit slide together smoothly. You can line up as many modules as you’d like, creating a fully customizable wall of organized hardware. The dovetails fit with light friction—tested on the Bambu Lab P1S—so they hold firmly while remaining easy to adjust. Each module includes a mounting hole for wall attachment, though in most cases you won’t need to screw in every piece, depending on your setup. I printed in PLA, and the parts feel sturdy enough for standard shop use. However, you can easily print these in PETG, ABS, or other materials if you want more durability or better resistance to heat and temperature changes. I have not tested other materials so your results and the fit of the dovetails may vary. Lastly, in my print I have placed a small brim to keep the dovetails a little tighter, so when pulling these off you may need to use a small blade to clean up the tight corners.
