I built this fence to prevent bottles from falling out when opening the refrigerator. It measures 180 x 61 x 5.9 mm. There's a 2.9 mm gap between the legs (note that the legs are flexible when using PLA, so if your compartment walls are larger, it can still fit).

I added the f3d file, feel free to edit it as you need it. It'd be nice if you'd share your version in “makes” or upload it as a remix. 

Commercial use: My goal is to make everyone happy. If you'd like to sell it as a product, feel free.
