I was surprised at how expensive an OEM replacement for a cargo net retainer costs for my GM car, so I made one. Printed in two pieces to eliminate supports. 3 thread sizes for the threaded post post are provided; 7mm, ¼-20 UNC and 5/16-18 UNC. STLs included. Center post is labelled with the thread sizes in the .3mf.
