Bee Hive feeder PET Bottle

This are a beehive feeding adapter for Norwegian standard hives. It fits 1.5L PET bottle (Norwegian standard). No support needed, I've tested it and it works just fine both with water and "sugar-liquid". Inside there are a water lock, witch prevents every thing to leek out. I share the source code for openscad so feel free to modify.

I made a important upgrade v3 has a drain hole to avoid killing bee's when raining.
