I really liked the simplicity of the original design (https://www.printables.com/prints/46707-simple-pliers-holder), but my very small workshop has limited wall space - so I designed this version to hold three pairs of pliers, held by three screws. I also increased the wall thickness a little to 1.8 mm (prints very well witha 0.6 mm nozzle, but 0.4 mm should work just fine as well).
