Long bobbin case for vintage sewing machine shuttle bobbins

thingiverse

This is a case for storing long bobbins specifically designed for vintage Singer sewing machines like models 27, 28, 127 and 128. It can also work with other machines. The number of bobbins that can be stored ranges from 6 to 12, depending on your needs. You can easily customize this feature by making adjustments if needed. For reference, a 7-bobbin STL file is already included. Due to its popularity, I have made an update to this design, bringing it to version 2. It now comes with hinges that make the open end much easier to grip and pull open. To assemble this storage case, simply print both halves. When attaching the hinges, cut a taper on one of the hinge pins so that they fit together smoothly in the open position. A bit of effort will be needed to get them aligned properly. The two halves are kept closed by simple friction at the opening edge.
