Info: The wrench fits for anglegrinder nuts with 35mm hole circle diameter. But like some comments mention there are also other types of nuts with 28 or 20 mm hole distance. Check your dimensions before you print it

Found this Idea in the video of pocket83 and had to do a 3D printed version of it

The model prints without supports if you use 0.2mm layerheight.

For furhter hardware you need at least 2 M5x20mm hex nut screws.
You can screw them directly in to the model. If the fit is too tight you can tap the holes before screwing the screws in.
