eSun PLA Dry-ish Box kit

thingiverse

I designed this project to fit the standard 1kg eSun filament box after struggling to find a suitable sealed container. The kit includes an insert through which you can feed a standard 4mm PTFE tube and optional rollers for smoother feeding. Since eSun doesn't provide resealable bags, this is just a simple way to keep their PLA filament fresh without too much hassle when using the material or reusing the container. 2x 608 (skateboard/fidget spinner) bearings or an equivalently-sized substitute are required for the rollers. I want to emphasize that this design is not a proper dry box. I wouldn't recommend using it to store nylon or any similarly hygroscopic material expecting it to remain usable for an extended period. You could probably make it so with some duct and foam tape but that's beyond my intent. As always, the photographs are of a near-final prototype.
