Cannon powered by printed spring & cannonball

thingiverse

This is a remix of an awesome design by rdg175's 12 year old son, of whom I am extremely jealous. The kid's got mad skills. My remix allows for spring replacement if it breaks. Spring, rod, and gun have been separated. The rod and cap (end of rod that pushes ball out of cannon) have been modified with screwed ends (male and female, respectively) to allow for easy attachment when replacing the spring. Also, Simplify3D couldn't properly slice the original due to non-manifold edges. I ran all the parts through Autodesk Netfabb 2021 and cleaned them up. The parts sliced perfectly afterwards. Be sure to check out their original design, if you want to print the cannon and spring as one piece. Edit-10/22/2020- Uploaded the wrong file for the rod. The one I had uploaded didn't have the threading on the end. I have now uploaded the correct one, so it can be attached to the end cap. Sorry about that!
