Bobbin Sun (Bobbin Holder)

thingiverse

A no-tangle circular bobbin holder for Class 15/A Style bobbins (the most common kind). One "sun" carries 10 bobbins. The clips pull the bobbins into pyramid-like protrusions that bear against the thread whether the bobbin is full or nearly empty; this prevents the thread from unwinding, assuring no-tangle bobbin storage. Recommend PLA or a similarly rigid material. In any case, consider printing solid or nearly so. One finds in one's 3D printing career that solid prints are just worth it.
