I was looking on Printables for a hex key holder to fit my hex key set but didn't find one that would allow for 7 and 9 hex keys, so… I made one !
The holder fits 1.5, 2, 2.5, 3 up to 9 hex keys.
The top of the holes are round, and then tapered to hexagonal, so that the keys can “align themselves”.

The mount is basically a french cleat, After testing, I had to put the hooks on the top of the part so that the whole assembly didn't tilt forward once installed, so this part must be printed with supports.
As always, share your makes, and if you have some improvement ideas, just ask !
