About this 3D model

These inserts are for an old model for spool drawers, I have received a ton of spools over the years and ondered what do do with all the empties. Someone was smart, and made a model for a drawer that fits around empty spools. These inserts fit inside those drawers and allow better organization of all the small parts that I am hoarding, small machhine scres, connector bits and bobs, mini drill bits, etc.
