Filament Spool Storage Container from Food/Cereal Box (Simple Version)

Convert your 4 l food storage container into a filament storage unit for 1 kg spools.

This custom insert provides a base insert for the container that wedges the narrow section apart to provide more space so that the spool is not deformed. It is not optimal but it should work. Use foam tape (e.g., 3M 4229) to stick the insert to the bottom of the container.

This is a simpler version compared to my other project based on a more suitable container:

Details

You can fit some 1 kg spools with a diameter of 200 mm and a width of up to 65 mm without the insert.

The caveat is that spools with a width of over ~62 mm might deform slightly over time because they are wedged between the indentations at the side of the container. The custom insert is designed to increase the space.

Why did I previously say not for filament spools?

• I was looking for a more universal container for typical spools with a width around 70 mm.

• My plan was to insert a ball bearing mounted spool holder that allows turning inside the container so that the filament can stay inside while printing.

  • This is not possible even the ~65 mm wide spool that is illustrated on the photo. Without the insert, it fits okayish but it will definitely not turn freely.

  • Deformed spools might not turn smoothly in certain spool holders that hold the spools on their edges instead of the hub, e.g., my Filament Dry Box from Food/Cereal Storage Container (Advanced Version) project with a different box.

• The custom insert I made can counteract some downsides of this specific container making it more suitable for filament storage.
