I got tired of my mini wrench set being mixed in with my other wrenches so I built this organizer. It is made to work with the craftsman wrench set similar to this one: https://www.amazon.com/Craftsman-9-42319-Standard-Combination-Ignition/dp/B00065T02S

This is a very simple print requiring no support material, just a little bit of bridging.

Update 5/20/20 No reason all of y'all would need to rotate the stl to the correct face each time. Instead, I updated the part file so it will open in the correct orientation.
