Male to Male Hose connector

I needed to extend a hose by using a Mail to Male adaptor, so I used this tap connector as a starting point. 

I've not yet tried printing the rubber washers in TPU, as I had a couple. I'll give it a go shortly and post that if successful.

Cut off threaded section, duplicated the male connector end and flipped it added it. I made a couple of small dimension tweaks to make it fit my female connector.
