did you ever get an answer on this? I was wondering the same thing. Looking at all the makes here and on Sraf's, most people went with 20% infill even though the guide says 10%.
And no one mentioned top or bottom layers, I printed one with 2 top and bottom layers and one with 0 top layers and 2 top layers. Trying to figure out which would diffuse the light better. And of course any chance to save time, material, and weight is nice.
