4L Cereal Dry Box Lightweight Hydrometer Insert

This is my take on a dry box system after using many other models.  

I wanted a very lightweight insert to pair with my desiccant container for when I didn't need a full roller system, it is less than 30g.

This is is just the base without the rollers and other models.  

If you're looking to do an external dry box filament feeder, check out this model, which uses this insert as its base component:

Enjoy!
