Silica container

Silica container designed to use the cap with the gasket of the cereal box, 4 holes for M3 screws. To replace the silica, simply open the cap with the gasket, without having to open the entire box. To protect the filament from silica dust, I recommend using a sheet of paper towels as a bundle to hold the silica. It also facilitates the change of silica when saturated. Compatible with modular & minimal filament drybox rectangular hydrometer.
