2 Liter Bottle Funnel

I needed a funnel to transfer something into a 2 liter bottle and I was surprised I couldn't find one on Printables. So I made one that screws on. 

It took some digging to find what the thread is on a standard 2 liter bottle so in case anybody finds this, I believe it's a 28-SP400 thread and the FreeCAD ThreadProfile workbench has it as a preset.
