need a little advice on ABS wall thickness for my first project.

I'm getting ready to send off my first design to a printing service in a day or two, but I need to refine it a little. It seems a little thick, but that's because I'm not sure yet on how thin I can make weight bearing sections when using ABS. I have attached my design, and you can see that the thinnest sections are 4 mm. It needs to be able to hold an eye-tracking camera weighing about 200 g. Can I get away with reducing it to 3 or even 2 mm?
