Are you saying that even as a single object printed this could have been printed quicker and better? Or are you still pointing out that a more modular approach would have allowed for each section to be aligned and printed quicker and more efficiently?

Yes and yes
The supports you`ve used were way too... dense
You`ve got floating elements, not attached to the main model, I`m sure you arealdy found that out, some of the supports for various elements are very flimsy/barely attached to the main model.
If you separate the top of the model you can move very close to the base, which means there are almost no support
The top of the model is the reason why the supports are needed, overhangs.
If you separate the walls and create a model for each, you can make them parallel to the base and depending on how flat they are there will be no supports and rigidity will be higher.
Ive attached 3 pictures, first is the way you printed the model, second, to compare with your default printing position, saves a good chunk of time...
I know you`re thinking, "its only 30 min more", true, but thats only one piece you`ve printed and all I did is rotate the model so there is minimal supports that need to be printed.
Print for 2 weeks straight different pieces and that adds up, to the cost and time, just wait to fail or having to replace printer parts and you`ll get it.
Third is a little bit of an example on what do I mean by the top of the model, red line indicates where the separation should be.
The reason I`ve asked about how strong your modelling skills are is because if takes you twice as long to split the large model in smaller models than for the printer to do the whole model in one sitting, is not worth it.
I hope this helps and I repeat, modelling and trying to get exacly the shape you want is harder than anything else you`ll need to do after that but dont give up.
