Force support generation on build plate, unless it's not possible

You could try normal snug supports and set a top and bottom z distance for easy removal.

<nevermind… I tried my idea and it didn’t work.>

This is a really interesting question to me, so I’ll be following to see if anyone finds a solution.

Yeah quite tricky, for the moment I have chosen to curse myself with thousands of extra supports, waiting to see if anyone else has some clues.
