I'm a fairly new bot-master, so maybe you can chalk this up to stupidity. I saw this post about louis generating code that made the tornado solid, so I turned my infill solidity to 0, but the build still created a top and bottom to the tornado. So, it's a hollow tornado with a flat top and bottom.
Any ideas as to what option I might have missed tweaking to make it completely open?
(on a side note, having printed and tweaked for less than 3 days so far, I was surprised the top of the tornado bridged without issue or sagging!)
