About this model

I measured a class 15 bobbin, and created a model based on that in freecad. I measured using a regular ruler, so the precision is not great but it has been tested and was functional in a sewing machine that required class 15 bobbin. EDIT 1: the v3 model is printed in two pieces that are easily glued together (I used super glue). This eliminates the need for using scaffolding, which results in a clean print that is better for bobbins. I'm still learning cad, but I want to make some adjustments so that super glue is not needed. I also need to stress test this, but my girlfriend sews as a hobby so it isn't in use constantly. If you have any ideas for feedback, let me know!
