Touch and sew bobbins are an odd design, they don't fit in standard bobbin cases and they are generally a pain to store. This case provide convenient storage for up to 23 of such bobbins.

The bobbins rest in a compact arrangement at 45 degrees to the horizontal and slide out easily with use of the thumb. The lid is kept in place by simple friction between the tabs.

The lid needs no support. I printed with supports for internal surfaces on the main case body, then pulled them out with long-nosed pliers.
