Storage Bin Organizer

Desktop storage organizer for storage containers approximately 9" X 5". These two examples from Harbor Freight, https://www.harborfreight.com/18-divider-storage-container-94456.html, and Plano, https://www.planooutdoors.com/collections/tackle-trays/products/prolatch-stowaway-3500?_pos=2&_fid=21f835c9a&_ss=c, are known to fit. Also in the files is a shelf for putting smaller containers on the organizer. First plate is the base shelves, second plate is the add on shelf and keys for connecting the shelves. I used CA glue to glue mine together. Printed in PLA.
