About this 3D model

I created this toy to look at a simple press fit, spring properties of PLA and to make something fun. See PDF for basic info and instructions. Note: Uses two hands, one to hold the shooter and one to pull back paddle to shoot Will hold and shoot anything that can fit into the funnel. Will shoot a pellet almost across my garage so, please be careful. Really not for children. Don'™t know how long the spring properties of the paddle will last. Dozens of shots so far for me. But, I do know if you hold back the paddle and leave it there long enough it will take a material set and not provide the same forces anymore.
