Medical Filing Cabinet Ideas

A while back I got this Medical cabinet for free, and it's just been a catch all for a bunch of random stuff. Each section is about 12.5" tall, and 9.5" between separators.

Right now my only plan has been to make some wood boxes for storing various parts or tools to clean it up. Maybe make some large plywood or metal doors that can have various tools, parts or similar hanging off of?

Each separate section can be separated if needed and attached elsewhere if there is a good idea.

Right now it's just like a big exposed junk drawer, and there has to be a some good improvements. It's fairly heavy duty and stout enough to be completely full of paper.

I'm open to anything.
