It's a functional, printable, and durable keychain that's aesthetically pleasing.It's already been 3D printed and prints without any issues.I printed it at approximately 3.5 cm.

It comes with a Blender, .obj, and .stl file. It also comes with a file prepared in Anycubic Photon Workshop with supports for printing on an Anycubic printer if you have that type of printer.
