Spool for filament samples (Anycubic i3 Mega)

thingiverse

I'm designing a simple spool to house sample filament that comes with a purchase of filament. The sample spool consists of two parts: version A for larger amounts, up to 30 grams, which requires printing 'sample_spool_p2a' and 'sample_spool_p1' covers; version B for smaller amounts, between 11-15 grams, requiring the same covers but with a different design. I've included step files so that anyone can modify this design as needed.
