My Wife's Watertight Vase

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:2908888.

My wife wanted a vase that would give a bouquet a nice presentation. Watertightness was not an option but an absolute requirement ... So this came out. It can contain quite a lot of water (>2 litres / 0,5 gal) and she should be able to move the vase WITH the water without the vase breaking apart. Wife-proof so to say... ;) The form of the vase is one of the supporting elements. The plastic I choose is PETG which I used already before in similar projects and has a good strength, layer adhesion and a tiny bit of flex. Wall thickness is another parameter.
