Difficult print orientation

I have this difficult design and can't get it printed properly.
if I print in this orientation:

I get support structures stuck in the lower thread, which destroy the thread once I remove the support.
If i print like this:

it works best, but the upper threads turn out relatively bad
if i print like this
https://ibb.co/dhJyMd
I have support structures in the small threads that I can not get removed anymore.
Any tips on that? The threads have to turn out nicely, since the whole thing has to be air and water tight. Also I don't have access to water soluble support printing.
Re: Difficult print orientation
What slicer are you using? Simplify 3D supports custom support positioning (but costs $150). Cura allows customizing supports, but is more difficult to work with. You could try to print it inverted as in your last example, but avoid support around the threads.

Re: Difficult print orientation
I am currently using slic3r but I've worked with cura also. How would I customize the supports in cura so that there are none in the threads?

Are you by any chance printing with PLA plastics? Also you might want to try out toning down the support threshold to about 35' or so and see how well it goes?
Rather, I advise you to revise your design since the long hose is the one you will waste plastic with. You can make it shorter same level as the lid then you attach any rubber hose through it to make it longer to your heart's desire.
Make the fan at full speed for printing pla so it will not stick to the supports.
Re: Difficult print orientation
Hi, thanks for your answer!
I am indeed printing PLA, but I would also have access to PETG and Nylon at the moment. However I would prefer, not printing nylon for now, since I haven't ever done it before. Do you think another material than PLA would be more suitable for these kinds of prints? also if I make the hose shorter and then attach tubing, do you think it will be water tight? The meaning is, to apply air pressure through the first hole, to have fluid pressed through the long hose ...
Re: Difficult print orientation
If you orientate on the last direction (top down)
and put minimal thickness sacrificial discs on the two nozzle tips, then use support from build plate only, then you shouldn't get support in the area of the small screw threads.

Re: Difficult print orientation
PLA is the easiest material to print with as long as you have print fan attached and blowing. I've been print ABS for at least 2 years and I gotta tell you that abs can be frustrating most often. You can't do long prints with it because it will peel off unless you have enclosure ( I didn't). Nylon, I don't have experience with it but I do heard that it is prone to moisture before printing. Best bet is petg.
But material selections are highly dependent on your applications. Currently I am printing tantillus' parts with pla because those parts won't be handling high temperature stuffs.
What does this cap do actually?
If hygene isn't a concern, shorten the long tube, then make a rib/ridges that is similar to water tap's end. Then you secure the hose with ziptie.
Re: Difficult print orientation
This is a cap for a falcon tube (common disposable tube in labs). It is supposed to be connected to a syringe filled with air. Once you press the air inside the tube, the fluid inside is supposed to move up the hose and then through tubing into another tube.
Re: Difficult print orientation
You can try joan's suggestion of supports on the build plate only and inverted orientation instead of full support and see how well it goes
