The file 'Mini Spool 3D Printer Model' is (stl) file type, size is 2.8MB.
I ordered a half dozen samples of flexible filament that came in bagged loose coils. I didn't have a good way to run them on my machine because I recycle my empty spools pretty regularly, and it would be silly and take up too much space to wrap little 50g samples onto full sized spools anyway. So... I created this design as the solution.
