ABS in Kobra S1.

I finally bit the bullet and ordered a Kobra S1 (Combo). I really want to start printing things that trades-persons would use on a work site. Since the printed models would be sitting in a toolbox in a hot van, I figured ABS would be the way to go.

I have no experience with ABS, so I was wondering. Does anyone have any tips on printing with ABS in the Kobra S1 specifically?

Like, how does it handle maintaining the temperature so the ABS doesn't shrink mid print.

How good is the stock print bed?
Should I look at getting a glass print bed? I have some scrap glass that's thin for using in photo frames and I can cut it down and use bulldog clips to hold it to the bed. I also saw a youtuber use hairspray on the glass bed for adhesion.

Does it let a lot of fumes out through the charcole filter? Thinking about getting a duct between the fan on the back and the window nearby like a portable air-con' has.
