I think you are correct on the complexity stuff. It is intimidating but two things led to that - the rise of people downrating models that are beyond their capabilities, and a lot is leftover from the earlier versions where there was all the gluing with lots of ways to go wrong.
I think I will trim it down, though. Thanks for the critique. The only trouble spots really now are painting it to seal it and soldering to those hygrometer battery terminals. The funny thing is the last one I printed was the tightest to air and best finish, etc, I was using filament that was nicely dried. So those without dryers but having moisture issues will likely see the same thing - if they print an air dryer it could be leaky. Kind of ironic.
