This model is a simple, small tray/shelf/holder that clips on the corner of a Samsung refrigerator adjustable/removable door shelf. It is designed to hold small bottles that are 18mm in diameter. There is a single version and a dual version. No supports are necessary. The models are designed to be printed upside down, which is the position they are when downloaded. There is no post-processing. Just print it and clip it on (if you have this type of door shelf). It stays in place nicely with friction. The model can be modified for different purposes, if one is able.
I would print the model with white filament, so that it blends in better with the interior of the refrigerator. I think it looks better when it is printed with 100% infill – there is not a huge filament use or print time difference between 100% and 15% infill.
I included a photo of the refrigerator model information. I assume that various Samsung refrigerators use this type of door shelf because you can buy replacements on Amazon.
I designed these because a family member uses special eyedrops that need to be refrigerated. We store the bottles in a door shelf, but when the shelf is fairly full, or when the bottle tips over, it is annoying to dangle one's fingers into the shelf to try to pick up the bottle. This simple tray positions the bottle where it is easy reach. It makes me smile every time I don't have to fish for a bottle. Initially, I used the single version, but the eyedrops are frozen until they are needed, so when one bottle is close to being depleted, we bring out a frozen one and let it thaw in the second socket.
