The paper bobbins that came with the DMC storage box were not sturdy enough so I decided to print some. I first tried the Flexible "Paper Floss Bobbins" for cross stitch embroidery designed by OrangeTree_, but I decided that I wanted something slightly different.

These fit standing in the box. Apparently some prefer them lying down, in which case they need to be resized in the slicer.

Instead of the cuts usually found in bobbins these instead have holes like those found on floss drops, which I prefer.
