I'm trying to print this.
I have a brand new Anycubic Kobra 2 Max. And it gets to the same spot with this print and fails. I'm new to printing so I'm kinda at a loss where to go with this. I've searched and tried a few things online, but no help.

Now that little more information is being made available (though it is a G-code file), with credits to SE user Velvet has posted a reverse engineered view of the print object based on the available G-code file:
With the recently added image of the object (referred to as the saddle from now on) in Ultimaker Cura to the question, it becomes clear that the object (saddle) has been sliced unfavorably because of at least 3 reasons:
For aesthetic reasons; printing these curved like objects in this orientation, when approaching the top of the saddle the steepness of the outer surface reduces to zero, creating a rough top of your saddle. You see this commonly when you print spheres for instance, the lower part and upper parts are usually very rough.
For structural reasons; there appear to be attachment slots in the saddle.
Economical reasons; the current slicing orientation allows for the generation of many support material, this is a waste of resources and a waste of time.
Looking at the sliced file I'd tilt the saddle -90° over the X-axis, this would significantly generate less supports and will produce a more aesthetic print. You always need to try to orientate the print that you minimize the amount of supports, unless e.g. this is structurally required. Supports are always a hazard in printing parts; sometimes these get knocked over, or collect oozed material from the nozzle causing shifts, it is best to reduce these hazards, especially on big, long prints.
If this is the image you are printing in Oscar's answer. I would do what he said and print with the side away on the bed. If it is not perfectly flat when it sits on the bed, then either lower it or draw in a support block to be removed later.
I have three of these printers and have have many problems with them trying to print larger objects then fail as the "Y" motor cannot deal with the "normal" speed of the Anycubic slicer. The weight will cause the bed to slip at nearly each layer. The motor does not have enough magnetic strength to stop the motor when driven to the extreme fore and aft. It can't stop it on the correct position when the weight is over 1 KG. The momentum of the part just causes it to overshoot and the prints are all bad.
So anything that causes this has to be eliminated. The number one is to SLOW the print down and stop wasting filament when working beyond the limits of the motor.
Second is the X axis belt will also slip when the head is moving fast and hits anything in the way. This indicates a need to raise the head at least 1 mm when travelling. Anything that can cause the X axis belt to slip is a problem.
I also have three of the regular Anycubic Kobra Max and they don't have this problem printing with 0.8 nozzle and 100 mm per second.
When I get time to fix this issue, I will put a MUCH larger motor on the Y Axis and use a belt drive to insure it has enough stopping power to print at high speeds. It needs to just STOP at the forward and back limits of the print.
You should be able to print this without any supports at all if you use a SLOW down on any parts that extrude outward. Slow down to 25mm per sec only on any overhangs and lower the temperature a bit. For high speed printing you need to use about 220, and for normal speeds about 200 with PLA.
I much prefer the normal speeds and precision of the slower Kobra Max. I did make upgrades to all of the print heads with bimetal heat breaks and different internal PTFE tubing.
Printing a dome on top always looks bad. As the stacking of the filament makes for a jagged surface. This is why printing it "vertical" is best. and without all those supports.
