Why is this happening? I've tried different settings and the adaptive option as well, but I'm still having this issue.

I recently made a 3D-printed functional movie clapperboard for my son’s birthday party, and it was a hit! The design is support-free, which made printing easy. After printing, I carefully applied some force (as shown in the video) to unlock the joints and make it fully functional. I personalized it by printing details on regular paper and attaching them with glue. It added a fun, creative touch to the party, and my son loved it! Perfect project for makers and film fans alike! 🎬
