Wee!
My first blunder.
0.040″ is too thin of a wall. In my world, I do a lot of 0.040″ thick walls–in aluminum–in parts that are 1/4 an inch big. I found some old shapeways parts and the thin walls are “squishy”
If I thicken the walls, I won’t be able to afford it, or won’t be able to over a short period of time.
If I build as is, it won’t work.
Thinking making a honeycomb like wall. A lot of work.
Thinking of making some sample wall sections using different design techniques and see which is stiffest.
What I do have going for me is that the majority of the internals are 0.080″, which I believe to be thick enough. With enough ribbing, the outer sections should be fine as well.
