I decided to organize all my parts into bins that allow me to easily see in a glance what parts I have. At first I was going to build standard shelving, but then I came upon a solution that's inexpensive, easy, flexible and fast. And it looks pretty cool, too!
Step 1: The storage bins...
The key feature for the bins is the hook along the back, that is designed to fit into their shelving systems.
These bins also have a 3" by 1" slot in the front for a label.
Other brands & models may work well, but I can vouch for these.
