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:

• I slice it as a “pseudo-vase” print
• Layer height: 0.3 mm
• Walls: 2 loops
• Infill: 0
• Top Layer: 0
• Supports: not needed
• Bottom Layers: 3 (for improved chances of waterproofness)

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.
