IBC Tank cap connector for rainwater collection

Don't really know how to describe all of that… I needed a way to connect my gutter to my rainwater collection tank because I can't just leave it open. mosquitos go in and reproduce like crazy and after that the all neighborhood is infected by those things… 

So here is my solution so nothing can get in or out (except from water obviously…). 

I didn't want to print a full cap so I used an existing cap an made a hole in it. 

Then you just have to glue the ring on it so the filter can just drop in it and the top connector just fit on the top. 

You just need to fit a piece of mosquito net on the mosquito filter (I use bungee cord to hold it)

If you have any questions, feel free.
