thingiverse
This is a handy addition that can be attached to your yarn bobbin clips to prevent the yarn from slipping off. It perfectly fits into the Essentials brand clips found at the dollar store or on Amazon, requiring two of these attachments per clip. There are two STL files available: one containing 12 items, sufficient for a single package of clips, and another with 36 items, enough for three packages of clips.
