Embroidery Floss / Friendship Bracelet Thread Organizer

I designed this storage box for my daughter, who enjoys making friendship bracelets out of embroidery thread/floss. It holds around 90-100 bobbins depending on how full they are. (The bobbins are the flat card type; see below for purchase links, or you can print your own from the provided model.) The box also has compartments for a small pair of sewing scissors and a winding tool, which can be clipped onto the edge of the box in two places to hold it steady while you wind.

The lid of the box is hinged, so you'll need three M3 screws to use as hingepins. The lid holds itself open at a comfortable angle of 105° and easily snaps shut with two print-in-place compliant latches.

Layer heights of up to 0.4mm and 15% infill are suitable and no supports are needed. I've tested with PLA but any material should work equally well. STEP file is included for easy modification if needed.

Here are links to buy the accessories in the US and UK. Most sewing and craft shops should carry similar items.
