Very nice design. Printed the first one at 100% on Genuine Prusa MK3. After cutting the bottom tabs and using a small screwdriver to break the rim free it still wouldn't turn. Finally read a lot of these comments and found that I needed to free up the two "bumps" on each leaf - that wasn't as easy as it sounds even with automotive feeler gauges - lots of time and flddleing. But it did work.
Then I printed a second one at 125%. Perfect. Cut the tabs, A few seconds with a screwdriver around the rim and it works.
