A cellular sculpture I designed. I used it as a candle holder, but when printed properly it can also be used as vase for flowers. To make sure the thing isn't melted by the candle I used a small, but high glass as container for the candle. The one I used has a diameter of 55 mm and is about 110 mm in height. I suggest you find a glass container first and adjust the model's dimensions accordingly.

The model is not too hard to print, although it is important to keep the speed of the printer fairly low. Most of this print was done at a speed of 60 mm/min. When the bottom part is used to store water I suggest to print the model with an 100% infill to avoid leaks.
