Dave's post inspired me to update my inverter ventilation with a more deliberate approach using a section of PVC pipe running across the back to a 4" fan on the end where it exits the cabinet. This combined with an inlet under the door on the near side should give plenty of airflow through the inverter cabinet. CAD rendering below shows the arrangement.
This update and some other changes actually simplifies the galley cabinet. Thanks again, Dave. My wife really likes George's pantry idea too so will try to make that part of the design. Great feedback, guys!
In the process of preparing the pretty picture, I discovered a modeling error and interference which I fixed. Can't have my battery switch protruding through the door.
I normally do drawings of all 3D design work as an accuracy check of the 3D model. Sometimes hundreds of dimensions are specified and entered during the process of creating a 3D CAD model. They are not readily visible until you go to modify something and then they disappear again. That is the nature/power of a parametric model. The only way to check them all is to regurgitate them on a proper drawing with views, details, and most of all tolerances. I would never release a model for someone else to make unless I had a detailed drawing to go with it.
But because I'm programming and machining my own parts, I can check things there and always run a new part if I miss something. Not so if I release data to one of my fabricators. I can't afford for them to run bad parts. And neither can they.
