Allen Hex Key Set Holder

My Kobalt allen key set started deteriorating, and bits of plastic were coming off in my toolbox and while using the tools, so I drew up a build to replace the standard set's holder. I also created one for the metric set as well, although the grey plastic hasn't started deteriorating as the red plastic did. I am also including another profile that excludes the hollow attachment point if you only want to print the tool holder itself for a different set of keys.
