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 when the sound of taps changes.

oyeah almost forgot to say the orientation for printing the parts is 180° to what you see in the 3d files
