My RC Car Pit Tool Stand. Again. :-)
It's now customizable, so that you can make it fit your own tools and even exchange parts to fit your needs in the pit.
The STLs include a 100mm and a 180mm (wide) version.
It also has a much reduced printing time, complexity, and best of all, you can now grab your tools easier, since the handle is now pointing towards you. My, why didn't I think of this earlier. :-)
PS: The predecessors (v0+v1) can be found here:
 Yes, there was also a v2, which was a complete failure :-)
PS: Missing modules can be downloaded from my things.
