A combination of this [spool mount](https://www.thingiverse.com/thing:1066342) and this [bobbin clip](https://www.thingiverse.com/thing:2630295).
Holds standard bobbins and clips into standard spools of thread.
To build this part, I imported stl files in Inventor, so the .ipt file isn't easy to manipulate.
