4L rice container dry box, only 25g filament needed

I usually use a separate 4L rice bucket to individually store opened filament. Bagged desiccants are relatively expensive, so I use 3A molecular sieve + color-changing silica gel desiccant to keep the filament dry. Therefore, I designed this desiccant box that can be embedded into the lid of a 4L rice bucket, and it only requires 25g of filament to print. The desiccant box uses a 1.5mm honeycomb mesh breathable design for air exchange, allowing the desiccant to absorb moisture from the rice bucket. The lid's top utilizes a 2.6mm honeycomb mesh, allowing observation of whether the desiccant has expired. The arched elastic bands around the sides can securely snap into the rice bucket lid without falling off. A 2mm baffle is reserved at the bottom of the main body to prevent the desiccant from crumbling and falling through the mesh after absorbing moisture, thus contaminating the filament. The compatible 4L rice bucket can be purchased on 1688 and is very inexpensive.
