After I printed this top I had the worst time getting it off my build surface. I ended up peeling off my tape to get it off! I designed it with tabs on it to help remove it from the table and it turned out they are too small and snapped of immediately.
If you can get a good spin it will spin for a long time since it is so heavy. Given the shape it prints with 100% infill no matter what your settings are so at 72mm it weighs in at 36 grams!
