I tried...but the inner spiral is too thin and unstable...when the fan turns on it vibrates and is loud

you can also try it yourself... open in BambuStudio and just change the infill to "Archimedean Chords"

i tried a spiral in color but it's also not that great :-)

thanks 🤜🏼🤛🏼i have different colors for every day off the week 🤣

thanks 🤜🏼🤛🏼

Thank you! Happy Printing 🫵🏼
