Magnetic quick change bit holder for hex bits and Wera ratcheting screwdriver

thingiverse

I work as a part-time mechanic at a bike shop and I'm not entirely satisfied with the layout of our tools. I have to keep walking back and forth to get the most frequently used ones, which are usually metric hex keys ranging from 2mm to 6mm in size. I prefer working with screwdriver-style handles for most tasks because they're faster and more natural than P-handles or Y wrenches. To resolve this issue, I discovered the Wera 816 RA ratcheting screwdriver handle, which has become one of my top tools. I paired it with a set of metric hex bits and was pleased with the combination, except for the occasional need to reach into my toolbox when changing bits. If only I could have all the bits lined up in size order so that I could easily swap out the quick-change end of the screwdriver onto it and retrieve the desired bit. Fortunately, I found a solution: a custom-made tool holder designed specifically for the 15mm quick-change head of my Wera ratcheting screwdriver. This handy tool keeps all the bits organized in size order, held securely by a strong magnet that also serves as a mounting system for steel surfaces. To build this tool, you'll need: * A 3D printed version of this design * The Wera 816 RA ratcheting screwdriver (Other quick-change bit holders like the Irwin holder will also work) * A set of six metric hex bits or any other type of quick-change bits * A 60x10x3mm neodymium bar magnet
