Gridfinity Ratchet Extension Holders

Extension holders for 1/4", 3/8" and 1/2" drive extensions. Why are these different? Well, the 1/4" and 3/8" take up minimal space because they are half grids wide. I also didn't waste any space for labels, keeping everything as compact as possible. While all holders have 6mmx2mm press fit magnet holes, the half-width holder will probably need to be glued. I recommend magnets especially for the half-width holders to help keep them in place. I had a short 1/2" extension that was able to stand upright in my toolbox, so I included that holder as well. All holders are 3U tall to match my other accessories. Modeled with Craftsman extensions, but I am sure other brands will fit. If not, I can easily generate an alternate size if you need one. 1/2" holders were tested with Pittsburgh (Harbor Freight) impact extensions and Craftsman non-impact extensions.
