About this 3D model

I getting my first 3d printer in the next few days, so I'm learning how to make .stls. A few years back I bought a used toy that originally had two swords, but it was missing one. this file was made to scale, so when it prints it should fit in the robot's hand. This part was made with Tinkercad. Edit the part online at: https://tinkercad.com/p/acc04245fdb8423b/181
