The first one (smaller one at 100% size) did not work. The inner petals seemed to be fused to the innermost dome. The outer ring came loose directly from the printbed. I tried for almost an hour to free them, but I only managed to get loose one single petal. And by then the print looked really bad because I got impatient and might have overused the knife a bit...
Then I printed a bigger version (120% size). After cutting the supports on the bottom it worked right away. And it works beautifully! What an amazing design!
