Compared to the previously designed cyber dart, the blade state has been redesigned, along with a ring-shaped structure suitable for hand rotation.

It is not recommended to print with silk filament. Silk filament tends to extrude thicker lines, and the friction will also be relatively higher, which will greatly reduce the spinning experience!

I also found that using the tip of this dart to open express packages is very effective.

If you find that it cannot rotate after printing, you need to use needle-nose pliers to grip the center and rotate it a few times for it to spin normally.
