I have plenty of stuff to fill them. I have boxes and totes that need sorted for the last three years. I know where there were angle iron dollies with cast iron casters. If I cut one down so I can pinwheel this on there I can go four wide and seven high and be able to roll them under my shelf. See blueprint below… There are covered in oil so that’s a project to get them cleaned up.

They are made to stack so thats nice. I have Midwest bins 8’ as a random hardware wall and an old hardware store spinner bin stuffed with who knows what. I need the professional organizer from hoarders. I have safe deposit boxes I wanted to make into drawers. The have lids to hopefully keep the nice out.
