Fridge Deodorizer

Mess-Free Fridge Deodorizer

Simply fill with Baking Soda (sodium bicarbonate)

I went through many iterations and a lot of trial and error to get this version right! This deodorizer is designed to maximize airflow—letting the baking soda "breathe" to absorb odors—without making a mess. It features a "double-wall" defense: the inner wall has fine slots to keep the powder contained, while the outer wall catches any stray grains in the channel between them.

Placement Tip: For maximum odor absorption, place the deodorizer near the air outlet of your fridge.

Printing Notes: I used basic PLA, though this design works with any material. Please note that this model involves a lot of retraction; ensure your filament is dry to minimize stringing. This is especially important if you are using PETG or other string-prone filaments.
