Compact and Modular Sewing Thread Holder

I made this modular sewing thread holder. Prints flat, parts snap together. Snap together the Leg pieces first to make it easier. Rows can interlock and the spacing between spools is very compacted. A revision is made where the interlocking row connector is a bit thicker, sacrificing some space if you were to connect individual segments together.

Different size spools can be in the same row. However if you were to connect the row to a different row, then size of the Leg pieces is based on the largest spool size. Otherwise the largest spool will touch the other row.

If you have Onshape, the sizes can be parametrically adjusted to account the Spool diameter as well as other dimensions of the holder. I don't really sew, so the sizes I have might not be standard.
