I designed this holder to fit my wrenches, so it's unlikely that it will fit yours perfectly. Therefore, I have uploaded the OpenSCAD file and you can adjust the variables s1 to s17 to match the width of your individual wrenches. However, be warned that I am a beginner in OpenSCAD and the code is far from perfect (It's horrible…).

I downloaded the knob from printables. It's a M4 knob.

Rather than focusing on the holder itself, the intention behind sharing this design is to inspire others to create something even better. Feel free to improve upon the concept!
