I used from 'Wiha tools table stand' the 'wiha-table-stand.stl'. This was a very good basis to add my own solution for holding R/C car typical tools. There STLs for hex driver tools and a bigger one for the wheel nut driver tool (marked with T).

With the little junctions you can choose your own count and order of your tool holders. It could be a little bit tricky to print the junctions in the right size. In my case I used glue to put my holders together. But the stands are still loosen, so I can pack it in my tool bag.
