These Dewalt 20 compartment pro organizers are great for storing small parts like M3 screws. The problem with these are that sometimes the dividers will lift up and let the parts mix together and you spend hours sorting out the parts again. I built these little storage bins to prevent the parts from getting mixed up and also being able to pull out that specific bin to use. 18 of these bins are the same size and there are 2 bins in the front that are larger.
These can be printed with the little lip for the labels to be put on.
