This design is a container for a 250g bag of dehumidifier (Calcium Chloride or similar). I've made the model for quick printing, and it takes approximately 1 hour.
Material Recommendations: I suggest using PETG due to its durability and chemical resistance. PLA can also be used but might have a shorter lifetime.
Printing Instructions:
Since Calcium Chloride will release liquid over time as it absorbs moisture, it's important to ensure the container is waterproof. I recommend testing the print for waterproofness before use. (My result with these settings is 5 out of 7)
Customization: The source OpenSCAD file is attached, allowing for easy modifications to suit different volumes as per your needs. Or you can just scale it in the slicer.
