My wife asked if I could print her a bunch of bobbins for her emroidery thread (she has about 200 colors from some giant batch she ordered online). She gave me a bobbin to use as a template. Five minutes with a digital caliper and TinkerCAD, and here we are. I recommend 100% infill as it is only 1mm thick -- I doubt you could convince your slicer to use less filament if you tried to print at a lower infill anyway.
By measurement, this is a perfect match to whatever brand bobbin my wife handed me. Best of luck!

Print any way you want. I went with fast and rough settings because I need like 100 of these things, and printing at finer resolution doesn't increase the quality all that much. :)
