Leaving my printer outside on the balcony. Temperature, Safety and Smell concerns.

I am planning on buying an 3D printer for printing miniatures for board games and I wanted to ask a couple of questions.

1. I am planning on keeping on the balcony of my appartment. Which receives direct sunlight as its facing east. In the summer temps can go up to 30c (86f) and in the winter in can go down to zero (32f). I am not sure in what to keep it. I can get an IKEA garden storage unit which is metal or a grow tent. I am worried that the grow tent might get too cold in the winter or the metal IKEA storage unit too hot in the summer.

2. Since I have people living above and below I am also worried about the smell most people are refering to (I've never experienced it). Will it be a problem even though it's technically outside and there is constant airflow.

3. Safety regulations. In my apartment complex you need to get approval to store flammable liquids. Gas burners for instance are not allowed neither the storage of petrol. I need a special license for IPA so I am heavily leaning towards Water Washable (I hear the Wargamer and Nova 3D have some durable ones that are water washable). What are your experiences with these resins? Also how does it effect the smell?

4. Printer model. Since I will need a heater especially in the winter I am torn on what model to buy. I am thinking about the Elegoo Saturn 4 Ultra 16K since it has inbuilt heating. Can I get away with a cheaper and smaller one (like the Mars 5's or Anycubic M4;s) and a heating until or heating belt? Is it safe?
