When using my Cobbler's Sewing Machine, removing the bobbin is not easy without a tool of some sort. This is simply looks like a popsicle stick with a embedded magnets at both ends. Just put one of the ends over the bobbin and it'll lift it right out.
It uses 2 rare earth magnets (I already had some from Harbor Freight item #67488). When slicing the print job, have it stop on the last layer before it covers over the holes that the magnets sit in, drop the magnets in, and then continue the print job. Make sure your print nozzle isn't magnetic!
I just stick the tool to the side of the sewing machine for storage.
