Jam-Free Cereal Dry Box

Filament Dry Box for Amazon Cereal Containers

This is a custom-designed filament dry box made to fit the standard cereal containers available on Amazon. After experimenting with several popular designs and encountering various challenges, I created this version to address those issues effectively.

Features and Improvements

No More Filament Jams
The filament feeds between the two rollers, ensuring the spool rolls smoothly instead of lifting when snags occur, greatly reducing the likelihood of jams.

Support-Free Printing
All parts are designed to be printed without the need for supports, saving time and material.

Accommodates Various Spool Sizes
Compatible with spools ranging from 35mm to 70mm in width.

Material Efficiency
Uses 25.9% less filament compared to similar designs (101.79g vs. 137.35g).

Rolling Axles for Better Performance
Rubber hose on the axles ensures the spool rolls reliably instead of sliding.

Easy Hole and Tag Placement
Includes a drill guide for accurate filament passthrough placement and a self-centering tag design for hassle-free alignment.

• Effortless Plug Removal
  The tapered plug design and enhanced grip on the compression fitting make it easy to remove the plug or Bowden tube.
