Spring Powered Cannon!

thingiverse

Designed to impress, this futuristic cannon is made with precision using Autodesk Inventor and engineered specifically for my Physics teacher. With a versatile 2cm barrel, any projectile that fits can be launched with incredible force. After rigorous testing with multiple springs, results show that most soft compression springs are capable of shooting objects at least 15ft into the air. Scaling up to normal size is essential, so remember to adjust by 10x or 1000% to avoid a minuscule cannon! This minor adjustment corrects an automatic unit switch when importing parts created in mm into slicers set for cm units. The manual contains essential assembly guidelines. When printing, it's crucial to use the recommended 200 micron layers and speed of 80mm/s to achieve optimal results. Remember to securely attach the cannon pull knob to the shaft to prevent loss when operating. For successful construction, ensure that the spring is inserted first, as some may find aligning the cannon shaft into its designated hole challenging but doable.
