Printed great no supports needed. Not sure if I'd recommend silk due to the issues I had. Maybe more walls to make that area stronger. Going to try in another type of filament. I glued the tab back but another piece just broke instead.
I've found it varies based on the filament used. Generally it seems to open and close as intended with higher quality filament, and that is further impacted slightly by the color, as darker filament seems to expand less when printed.
