Added a new print profile with newer and better version

If you too, like me, have problems with wasps and hornets in your garden, you will have heard of these DIY traps.

Here is this very simple version that I designed that allows you to use empty plastic bottles and hang them under tree branches thanks to the ring provided. It has a dome shape that serves to prevent rain from entering and helps spread the smell of the trap. 

The 3 hooks inside adapt to the neck of the bottles and hold them without problems, I suggest using petg or abs to print it. 

This version works with bottle necks with a diameter of 22-26mm as you can see from this photo.

For other diameter just scale the model.

I hope I was helpful and if so let me know with a comment or why not a boost, thanks.
