The file 'Yarn Grommet For Crochet Yarn Bag 3D Printer Model' is (STL) file type, size is 248.5KB.
It's a hard grommet (for lack of a better term) you can stitch in to your crocheted/knitted yarn bag, similar to the slots you see on yarn bowls. I lack the patience to refine it, so I highly encourage someone to remix it. Still, it works well enough. I printed it with woodfill pla which I then put a slight stain on for "classyness". It'd work fine with whatever, though.
