I designed a combination wrench holder after struggling to find one I liked. This is based on a generic wrench holder that gradually increased in wrench size and depth. I used a 3x5 Gridfinity base for the 13 wrench holder and a 3x4 for the 11 wrench. The wrenches intentionally hang off the sides for both easier access and allowing to offset them to a side if you have layout considerations for your tools. I kept the magnet holes in the bottom but you really don't need many because of the weight of the tools.
