A friend and me rigged up quick and cheap to build filament storage using a bucket from Biltema (A Store in Sweden).
 

Required Parts

• The Bucket: Plasthink med lock, 10 liter - Biltema.se
• The water Absorbent Material: Fuktslukare, refillpåse, 2 kg - Biltema.se
• Some W-Profile for tightening

Assembly:

1. Print the Parts
2. Glue the “Spinner” to the bottom of the bucket.
3. Add the Bearing into the opening of the “Spinner”.
4. Insert the grill on the top and pour the moisture absorbing material into the bottom.
5. Add the “Spool Holder” into the Bearing, add glue if it is loose.
6. Glue W-Profile into the lid
7. you might have to grind of a bit of material where the lid clips into the bucket so it will close with the profile.
