15mm pipe connector

I had 15mm copper tubing laying around so i decided to make a connector which allows me to use it with the modular mounting system.

The connectors have flat spots between mounting holes and pipe connect which allows for a pipe to be hammered in with the use of a vise. Its a very tight fit but allows for no glue to be used, set the pipe straight with the connector, a few light taps to check the alignment and then a few harder ones to drive the pipe into the connecter, the pipe is fully seated
