About this 3D model

This is just a random project I put together. Trying different things for next year. This looks much more promising than the standard wood catapults I have been using. Kids will actually be able to make modifications much more easily! *You may need to adjust the Axel size a bit. *Took me roughly 5 hours to create the body, and 2 hours to create the Arm and Axel. If you have suggestions on how to create this more efficiently, please let me know!
