Simple stand for those 0.5 liter bottles with the swing-top cork stoppers — you know, the Grolsch-style ones (type БП-1-500-НФ). Hole diameter is 69mm.

Scales up or down no problem if you need different sizes.

I'd go with PETG for this one — it's stronger and handles moisture better than PLA, especially if the bottle might be wet. Printed mine with FDPlast PETG at 0.2mm layers, 30-100% infill depending on how sturdy you want it. More infill = more rigid, but even 30% holds fine for just standing bottles.

That's pretty much it. Print, pop the bottle in, done.
