If you're cursed enough to live in North America, you need two wrench sets. I like the ideas of having both sets arranged in some kind of symmetrical fashion on my wall as in the picture (therefore resulting on asymmetric holders). While I was at it, I also drew symmetrical versions which may look nicer in a tool chest tray, or if you have only one set to hold.
The mounting holes are separated by integer multiples of 1", in order to mount on a standard pegboard sheet. If you want to you that route, there pockets are fit for BigRedButton's anchors (see link below)
I had good results (albeit quite a bit of stringing between the combs) by just printed in PETG using the default settings in Prusa Slicer with no support. The anchors pockets' ceilings are made in two steps for straight bridges.
The author remixed this model.
