Water cooling for E3D V6

Here's Water cooling system for E3D V6 hotend.
This cooling system works pretty well and I don't have any clogging issue, so I could use filament retraction for further distance like 5mm.
FYI, optimal retraction distance for me was 3mm.

I have made out of PLA printed part.
To make sure water proof, print this without any gap and use heat gun when you assemble.

I used latex for sealing but you can use silicon as well.
After assemble, make fasten with tie for each outlets and gaps, use heat gun when you fasten.

Also I used instant glue with baking powder for the top and bottom and joint of fittings.
First apply instant glue then put baking powder and spread it. Then apply instant glue on the top of it once more.
This will ensure the water proof.
