This is Bobino.

A small accessory that allows you to organize your sewing machine threads and bobbins by color.

A friend of mine was having trouble storing and organizing her sewing accessories. We went to look at what was available online and came across a multitude of accessories. Most of them were too bulky, impractical, or not suitable for 3D printing. Inspired by what we saw online, we settled on this design optimized for 3D printing in TPU (less than 3g of plastic per print, prints in around ten minutes, no supports needed).

Please keep in mind that this model is an early version, and that the associated print profile is approximate (my TPU spool was stored in a humid place for about 2 years so I have a lot of unintentional bridging that I didn't take the time to adjust)
