This Gridfinity compatible holder has one large space and three small spaces, in a 1x1 holder. It stands 12 units high. This fits a nozzle brush, an L-shaped wrench, and some nozzle cleaning pins perfectly, so I always have them handy near my printer when I need to clean or change the nozzle.
You can find all of my Gridfinity designs on my profile!
