A box for an engagement ring in the form of a flower that opens by turning the ring. Inside there is a heart on the stick in which there is a cutout for a ring.
Due to the print in place design of the model, I do not recommend printing too quickly and with a high layer height. Damage could occur when the mechanism is first moved.
After printing free the rotating collar from the base by lightly prying up on the collar carefully with a flat blade screwdriver. Work your way all the way around the base and then twist the collar while holding the base to free the threads.
