The file 'English Hex Key Holder 3D Printer Model' is (stl,3w) file type, size is 10.4MB.
This was a holder I made for my Craftsman hex keys that were just loose in a bag. There's a little nub in each hole to create a little friction with the wrench. For me at least, the smaller the key, the tighter they fit. They all stay in place when you turn it upside down but the larger ones aren't as tight.
The letters came in pretty good for 0.3 mm layer height too, so I don't think a smaller resolution is needed.
This may not have all the right long/short holders that you need for your set. If you like this but want a slightly different arrangement of keys, message me and if it's easy enough, I can tweak the model for the arrangement of keys you need.
