I’m just in the process of organizing all the junk in my garage, so my radar is tuned to clever DIY part storage ideas. This one from back in 2007 is by Instructables user tomward and uses ziplock bags inside binder pouches inside ring binders to provide three levels of organization. It looks very space-efficient, but falls short on one half of the part storage problem, methinks, which is allowing for fast sorting of the pile of parts you sweep off the bench when the project is over (or, if you’re like me, the bucket of parts swept off the bench over the course of many months’ worth of projects). I still think bins are the way to go.
