I’ve wanted to design and build the perfect tool holder for my Ender 3 v2 for a while now and finally had a chance to do it during the holiday break. I used FreeCAD. Here is the full design:

There are 3 parts connected with dovetails. If I want to change something in the future, I don’t have to reprint everything. This is the mount:

The mount slides into the 2020 rail slots on the top rail of the printer. It is snug enough that it will probably never move, but I went ahead and designed it so that the right screw holds it in place. That will be shown more clearly in a later screenshot. It is designed so that the left rail screw never needs to be removed so that the rail positioning on the vertical rail doesn’t shift.
Here is are the 3 parts assembled:

And here it is loaded up with all the tools I use most often:
[ATTACH=JSON]{“data-align”:“none”,“data-size”:“medium”,“data-attachmentid”:7416}[/ATTACH]
Of course there are other tools that come with the printer including the hex wrenches and the open-end box wrenches, but I don’t use those tools as often and the printer’s built-in tool drawer is perfect for those.
There is plenty of clearance when the print head reaches the top of the gantry:
