This is a balancing wine bottle holder. It is designed to handle most bottle sizes (full of wine) and neck sizes. This file should not be scaled unless you have a particular bottle you know will work.When placing in slicing program, rotate slightly to tighten the Y plane (this worked better on my Makerbot Replicator 2) for more accuracy. Print on it's side (half moon when looking down the Z-axis) and you won't need support structures. Prints really well with shells set to 2 and infill set to anything more than 5%.
