###Update: ###Added a version with a threaded lid.
This is an item that I designed and printed out of necessity, when one of those refrigerator experiments went terribly wrong. After hours of cleaning the leaky mess the remaining aroma was anything but appetizing.

This is a ventilated container that holds two semi-heaping tablespoons of baking soda. I printed two of these and placed them at different levels on each side of the refrigerator. In my case the odor was significantly reduced in 24 hours and gone in three days.

There is one top and two container files. One container file is for printing in vase/spiralize mode and the other is for normal printing. The spiralize mode prints faster but is weaker. I've tried both and they work. I don't know how long the spiralize version will last.
