Thank you for taking the time to my questions, indeed you are bang on the first pic shows a good print, I printed this way so the internals were good to check my measurements there are components to be located into this, and you are correct the outside which is important for cosomatic reasons was not good at all.
The second was an attempt to see if this gave me the best looking part which also failed, the face that was not supported dropped and also if you look carefully the is a flaw half way up the print that made this print mechanically un sound. This is a pro type of a part that will be thicker (big square in pi 1) at moment it is 2mm thick but will be 5mm and it will have a tube printed through the centre to conduct water. My thinking was print it in 2 pieces , 1, I didn't think it would print a tube very cleanly horizontally, and 2 it would cut down on print times instead of a 10 to 12 hr session (1) 6hr session a day???
I haven't had a good print out as yet I am trying another orientation as we speak based on pic 1, but with no supports. I do think that printing it all out as in pic2 seems feasable but also I don't exactly know how to draw my own supports, I am not adversed to trying though. I will post a couple of pics of the next printout if you could give me your opinion I'd appreciate it.

I'm going to have to make some guesses because you are leaving a lot out of what you say.
1) The first picture looks great. I'm guessing the bottom side doesn't look so good, right? And I'm guessing that's going to be the "outside" of the final part and you want it to look better? Please verify this is your goal.
2) The second picture looks great - I don't see a problem. The underside of that long "flap" seems to stop early. Is that the part you want to glue on? The flap? You want to glue very thin edge to very thin edge? I don't think that will work well. I'm just confused here as I don't understand your goal and I don't understand what the problem is.
It seems to me orientation #2 is a good solution but why not print the whole thing as one part? I know it wastes lots of support but so what? If it were me and I printed in that orientation I would turn off support and build my own support in cad as simply two walls that go all the way up with regularly spaced holes to allow me to cut it off later. It will need sanding and that edge will not be as pretty but close enough?
But even easier, I would print the part like orientation #1 but lay the side with the small hole in it flat and down on the table and the other flap in the air. Then I would change the model so there is NO BEND between the flap and the main section. Then print it and after it's done printing I would heat it up with a blow dryer or some hot water and carefully bend it into the correct orientation. I would probably build a jig to bend it perfectly. This jig would probably be made out of two flat stiff things like a table and a book cover or a table and a thin piece of flat metal propped up.
