4L Cereal Filament Dry Box

One of the dread of 3D printing is wet filaments - excessive stringing, uneven surfaces, extrusion issues, etc. 

If you got a similar looking 4L airtight box around, you can print these items to turn it into a filament dry box.

The roller parts should fit snugly. It is not necessary to glue them together but there is no harm if you wish to do so.

If you wish to feed filament directly from the dry box, you will need to print the lid and get the optional parts. Otherwise, you might want to check out the tabletop filament holder that works with this roller!

Do check out the humidity sensor/ hygrometer holder.
