Standoff for gravity spool holder

I created this model from scratch using Fusion 360 but I want to give credit to @volker_puttmann for idea. I copied the design but modified it so that the front end would clip perfectly onto the Manhattan Narrow Tall Open-Front Bins from The Container Store. These were designed to work with the 3D printed bases for the Gravity Spoolholder for MMU2s by @MichalFanta. They may work with the plastic bases from Prusa but not sure.
