About this model

I have changed the "bucket" to be wider for bigger "projectiles" and added a thumb wheel of easy range adjustment. But the bigger redesign is the fulcrum. I split it into two parts to be printed easier. Now the hole for the axle goes now through all the way, so a longer threaded is needed EDIT 4/30/2019 As mentioned below I managed to break/wear out the spring rather quickly. Hence I added a beefed up version. This might not be the engineering approach of Leonardo as he had presumably no access to rubber bands. I use my catapult as an office toy and am therefore not too concerned with historical accuracy. P.S. I will need to redesign the spring and strengthen it. It suffered material fatigue due to tightening the rubber bands to much, because I wanted to increase range and power. Stay tune…
