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.
