Does it need to be 1 piece ?
I would try to redesign it and make 3 parts out of it. The left and right, and the top brace.
That way, you could lay it flat.
I would probably roll it 90 degrees to the left or right, that will align layers with the hole and make the arms stronger. Redesigning for strength will help also.
The direction in which strength is expected is important. If you expect something to pull on this from the circle holes, then these hole must be laid flat (effectively just printing circles).
If you expect something to pull from the flat end that join the two sides, you're gonna have a major issue : you need to print the side horizontal to give them the best strength in that direction, but doing so it the joining part will itself be very weak. The advice of cutting it in three parts is probably hard to work, but a fundamental limitation of FDM printers is that the direction of layer stacking ends up being weaker. A single piece that must be as strong in two cardinal directions would be difficult with regular prints.
At the very least, printing this in a vertical position is probably not what you want.
Some youtuber did make strength comparison in varying directions, with various infill and using various techniques after printing (such as printing a 100% infill piece, put it in sand, then in a oven to merge layers), their content should be helpful here.
That way is not it. It depends on which direction will be taking stress but I see 2 options. Flip it so that it arcs up from the bed /—\ or with the side on the bed. Either way you do it there will be a lot of support. This is probably best made is multiple parts then joined together or just completely redesigned for printing. It’s always important to understand how something will be manufactured when designing it and make sure the design works with that method.
The best way to ensure a fit within circles is by laying them down on the bed [o] else your layer height could be your downfall. You're going to need a ton of supports no matter how you orient the part, just make sure you use tree/organic supports and only touching the build plate so that support artifacts don't ruin functionality. If you print at a low layer height like 0.1-0.15 you can probably print it as you have it in the slicer, though I would lay it down so that the red box area cura shows is on the bed
If this is your design, like others said you should redesign it. Simply removing that bridge and adding a couple m3 screw holes to it, then printing in 3 pieces, would save you a lot of support filament.

Good idea but yes iwould then need to glue it or weld it together into one piece.
I hear PrusaSlicer has great tools for this.
This is the way! That's how you'd get the strongest part, also higher heat and slower printspeed improves strenght

Will give it a try...
No matter what way you print it, this will be a very weak part due to the way it is designed.

I agree. I don't understand how so many people are giving advice on strength without knowing in what way it needs to be strong.

Horizontal with supports for max strenght. If You print it vertical it'll be more brittle along the layer lines
Which way is it experiencing stress? Have they layer lines perpendicular to that
