Zip tying the power connector directly to the board wasn't very sturdy so I created this mount for the power connector. Zip tie the mount where the connector goes and then use the nut on the connector to mount it to the bracket. When cleaning up the mount be sure not to remove the little nubs at the opening of the U. They are there to help hold the power connector in place. It should pop in with a satisifying snap. This mount may work for those who mounted their printrboard on the inside also.
