This is a gridfinity storage bin designed to hold 7 of The Perfect Bobbin. Each bin is 1x2x7 gridfinity units, and can be stacked with bobbins inside.

The slots are rounded and chamfered to make inserting and removing the bobbins easy, and there is sufficient clearance between each slot so a full 8m skein of DMC thread can fit on each one.

There are three bin variations to choose from:

•  2 notch (front and back) for visibility
•  1 notch (possibly for the beginning or end of a row of bins)
•  No notches, for best protection.

I chose the 1x2 size as a reasonable compromise between density and portability.
