In my days I have printed several wrenches, and it was a mixture of successful ones and failed ones.
A few things to keep in mind, scaling. I would not recommend to scale it smaller, the tolerance would become even smaller. If the current tolerance does not work for you, you can try to make it slightly bigger.
It is recommended to print on the low side of temperatures, to reduce any stringing.
Lowering the temperature of your heated bed could also contribute reducing the heat radiation that could make your gears sag, but you have to keep in mind that there is something to create adhesion. (If it is not heat, you could try blue tape for example).
A high resolution, thin layers, could also help to make the insides smoother.
What I found most crucial, is to get a great first layer. It should stick well, but you don't want elephant feet. You don't want to squash it too much because if the flattened layer will become bigger than the tolerance, it can prevent the wrench from moving properly.
We don't often release an alpha version of Ultimaker Cura... So what's different this time? This Alpha contains such a huge slicing engine overhaul that we really need your help!
We wish to celebrate and honor the innovators that push forward the field, technology and world. We opted to not present it as a competition or ranked list. Every innovator has earned his spot on that list in their own way. We also look at the 3D printing industry as a whole and not limit the list to those only using Ultimaker.

It is not an easy print, but doable. Good luck!
