I designed these to maximize drawer space use. The spaces for the wrench end is fairly wide on my Husky Ratcheting wrenches, but I think you may be able to adjust scale in the slicer for one axis only, making narrower spacing if needed (haven't tried, but should work)
I was going to print a strip of plastic that fits on top of these in order to place a label with the sizes, but I don't use these daily and it's not hard to raise the wrench from one side and see the size (I suppose that's the only downfall of this design, but can be added easily)
The author marked this model as their own original creation.
