AMS Dual Shelf Connectors

I printed AMS stacking shelves for my four AMS's, two columns of two units. I wanted to tie them together to keep them more secure and aligned on the workbench, so I grouped the head and feet parts together and it works perfectly. Ultrajaxel knocked this system out of the park, so if you are looking for a solution to stacking AMS's, look no further! Print with 100% infill for best results.  https://makerworld.com/en/u/2811301167/collections/109412
