First one has the pcb mount on the inside. Like this.

2nd one came out ugly. 
Working well so I’ll leave it for now. Instamporph plastic.
3rd one is still being debated. Might swap out the huge washers and 3d print something to fill that cavity. I like female on the board-side, but the way things were going for that board, the other way makes more sense, at least for now.
