My frist Model: Can i print "in the air"?

My first 3D model for the Anycubic Kobra 2 Neo. Will the print work like this? It probably can't print the middle floor 'in the air,' can it? Please help :)

Depends on the type of printing you do. The 3d printer will add supports to be able to print stuff elevated. Then those supports get broken off after the print. I think resin printing may allow you print supportless geomentry…. but I'm not sure.
FDM printers can hypothetically do bridging like that (it's called "bridging"), but they would need to be very well-tuned. Typically, you wouldn't want to print something like this. The print lines will likely sag. Can you design this in two parts and then use screws or glue to connect them?
I will use PLA.
Will the printer add the support by itself or do i have to set it up?
Maybe I could print it in two parts. Do you mean I should place my model on its side and print the other side separately?
There's no orientation of the model in which you don't have overhangs. Depending on what you're trying to accomplish, you might be able to split the part in two, design holes in the parts that you'd use to connect them, and print the top half and the bottom half separately.
The other option is to print with supports, though this model will create a lot of those - in my opinion, they'll be too much work to remove, and the surface finish would be awful. If you wanted to go that route, you'd set up supports in your slicer.
Most printers can handle a certain amount of overhang. So, print the model at a 45° angle. That will create the least amount of support material, plus you can place it where it can be easily removed:
Green = Support
Anyway: This is not a 3D print part. Parts like these are best made from sheet material. I'd laser the thing. Got a buddy who owns a laser cutter?
