This is a miniature version of the folding dart. After the parts were miniaturized, the strength of the pin was too low, so the protruding plug on the pull rod was changed to a hole for inserting a small piece of consumable wire. Each hole should be about 4-5 millimeters in size.
After testing it several times, I found that the support of the center of the circle is not easy to disassemble. You need to use a knife to modify it. Be careful not to cut your hands. Experts can modify the configuration by themselves.

The two holes on each lever are adjusted just right, but the other holes aren't. Maybe it's a problem with my printer. There's always one hole on each accessory that's a bit tighter. I can fix it with a craft knife.
It's not easy to make this, and I don't really care if you help me with the scroll. But I just hope you won't give me a bad review. It's really upsetting.
