Support for Bambu spools for storage

I found some people sharing their designs for storing Bambu spools in plastic cereal boxes, so I decided to try it myself.This design works well with:Yashe YH-308 cereal containers (available on Amazon.fr)CIMOYBAI round hygrometers (also available on Amazon.fr)Please share your thoughts on this design. So far, I still have some quality issues with the big ring holding the hygrometer when printing without any support, but it still works.
