Cyber Shuriken four-blade bearing spinning dart (can open express packages) toy

Cyber Shuriken four-blade bearing spinning dart (pointed tip can open express packages)

Can be printed without AMS, when slicing on the computer, use 0.2mm layer height and change colors at the 7th and 35th layers

I found that replacing the previous gears with bearings greatly improves the spinning experience

It is not recommended to print with PLA Silk filament, as PLA Silk filament tends to string more coarsely and has relatively higher friction, which will significantly reduce the spinning experience!

I also found that using the dart's tip to open express packages is very effective

It is also suitable for throwing and spinning outdoors
