This is the most recent update on the open vertical-storage-system project I've been building out for several months. Think of it as gridfinity for walls.
It's really been working for me as a project organiser and storage system - the idea originally was that you could put all the project bits in one (1) container, grab it off the wall, bring it over to the bench, hook it onto the wall there, and have all the parts right in front of you in one place, ding.
It also serves as kind of a reminder system since stuff is visible. Half the projects I had on it at first were tasks sitting around for ages but hidden in closets so I never got to them. But now I have visual cues, and all the parts are in one place meaning nearly zero barrier to work, so I get to them!
