I posted this project a while back in the Facebook forum, one of my favourites because it’s quick, easy, and functional
I used 3/4" Baltic Birch for the necessary strength in the hooks and also used a neat trick where putting a round-over bit in the CNC and setting the right height effectively turns it into an inverted router table. If you set the zero in UGS then you can repeatably return the bit to the right height, you’ve just gotta be careful with yourself AND set $1=255 in UGS to keep your stepper motors continuously engaged ($1=100 to revert this).
Credits to ivanseidel for the model off of thingiverse. A very great and useful model. I used it immediately for my grocery shopping. https://www.thingiverse.com/thing:26767
