本设计主体项链部分为一体式打印，采用铰链可活动设计。搭配心型宝石，造型优美。需要注意的是，打印项链主体部分的时候，如果不开群边将会降低打印的成功概率。The main necklace part of this design is printed in one piece and adopts a hinge movable design. Paired with heart-shaped gemstones, the design is beautiful.It should be noted that when printing the main part of the necklace, not opening the group edge will reduce the probability of successful printing.
