Gridfinity Step Drill Storage Bin

I’ve optimized my entire workshop with the Gridfinity organization system, and I needed a dedicated bin for my step drill bits. There were already a few models available online, but none of them matched the look, fit, or functionality I wanted. So I designed my own version — refined the dimensions, adjusted the openings, and added better spacing to make each bit easy to grab and put back. Like most Gridfinity projects, it’s a matter of personal preference — but I’m happy to share my design with you for download and use. I’m not entirely sure about the exact sizes, but they should be approximately 4–8 mm, 4–12 mm, 4–20 mm, and 4–32 mm. Please double-check your drill bits to confirm the dimensions and make sure they fit correctly.
