Bottle Holder

Just a simple bottle holder to hold my beer bottles in the fridge.
There were many already on Thingiverse but not quite what I was after.
These do not key together strongly, but just rest on top of each other on a pyramid.
There are to versions. One with a back and one without.
They take quit a bit of filament. I wanted 6 to hold a dozen beers.
They take the standard beer bottle diameter.
