Small update: print success, but the corners did lift some with no skirt. I'm going to try rabbit ears on the next one.
The side with support lifted... quite a bit. By far the easiest to remove support I've ever printed, lol. Thankfully that surface won't be visible, but I'm going to redesign that interface some on the remaining three pieces to be a bridge with two snap off pieces vs a support interface.
The ASA journey continues!
