stackable and threaded containers

I made this project of screwable and stackable containers. Apart from the base and the lid, you can print more intermediate containers according to your preferences and needs. I also made interchangeable labels that fit inside the respective label holders of each container to which you can attach stickers or, if you prefer, add texts via bambustudio.

ATTENTION: the intermediate containers have some imperfect lines at the end of the internal thread and the beginning of the base (as visible in the published photos). I tried to do countless tests to eliminate this defect but without success. If anyone can give me some suggestions I will be very happy. I published this project because I think it is still functional and also aesthetically very acceptable. Made with PLA MATTE BAMBULAB filament
