Most plastic filaments should be stored in dry conditions to avoid absorbing moisture. In the Dry Box, like in most other products with similar purpose, such conditions were achieved by using desiccant inside the tightly closed container.

The filament box can contain spools with diameters up to 210 mm and widths up to 80 mm, covering almost all 1 kg and less spools.

The model includes the desiccant container. I can recommend using the dryable silica gel with indicator granules. Please pay attention to keeping your desiccant effective. It needs refreshing from time to time to keep absorbing moisture.

If you have no refillable desiccant, the silica gel bags from the filament package should temporarily replace it. Put a filled desiccant container or a silica gel bag inside a spool before storing it in the container.

Boxes are designed to be stacked, making filament storage compact and adaptable to your workplace. Containers can be placed vertically and horizontally and have handles for easy storage management.

The box has filament holders. The outer holders work as showcases, so you don't need to open the box to check what type of plastic is inside. Cut approximately 60 mm of filament and push it in two holders. There are holders on both sides of the box. The inner holders fix a filament end to prevent filament unwinding and deformation.

Fix locks on each side of the top part. There are two fixators for them on each side of the top part. After that, push locks into the bottom part on both sides simultaneously to close the container.

To print one container, you will need about 400 g of firmament. No print supports are needed. STLs are already in the recommended to print orientation. Some parts require specific settings listed below:

• Top and “Bottom No Gasket” parts. Add an inner brim. 2 walls, 10-15% infill.
   
• Bottom part. Add inner and outer brims. 2 walls, 10-15% infill.
   
• Locks. Add a brim. 100% infill. PLA should be fine, but printing in PETG is recommended for better durability.
   
• Container and Lid. No specific requirements.
