Milwaukee Jobsite Organizer bin dividers. (48-22-8030 p/n)

These fit the bins on the regular organizers, but they do not fit the 'slim' organizer (half the height). Divided by 3 since it will remain secure and in place. Seals up against the lid when closed (your results may vary depending on the seal condition of the organizer).

The regular bins are good for larger items, but if you need to divide them up for smaller quantities this divider works great. I have one of these organizers dedicated to everything 3d printer related and another organizer dedicated to everything CNC router related. These dividers help address the smaller items and make most use of the organizer.

This site and the users are great and have been helpful so here's my contribution.
Enjoy.
