Sleeve for Costco NSF wire rack shelving

This is a remixed version of MexiMaker's model on Thingiverse.  I adjusted the position of the grooves and scaled it to fit the Costco version of this furniture.

This is a sleeve, bracket, or clip for your NSF style wire rack shelves that you probably purchased from Costco.  It's the part that holds the shelves onto the poles.  If you attach them to one of the spots on the poles with two groves near each other, position it on the top of them for best fit.
