I made two containers because
3D-printed PLA cannot be washed with hot water, which may lead to food safety issues.
A container can be used to hold clean chopsticks. When the chopsticks get dirty, they can be placed in the "waiting to be washed" container.
In this way, you can rinse the "container to be cleaned" with warm water, and the "clean" container can always be used to safely store food.

At the request of the user, a version with 26cm-long chopsticks has been added.
