printed in flex material, may be able to print in PLA I placed these on a 7.5mm diameter carbon fiber arrow from last season. I have a new 2 inch(51mm) cannon I am working on, and it has a barrel length of 5 feet. As a coaxial pneumatic cannon, it has a 4 inch(101mm) external pressure chamber with the barrel up the middle of it, and a floating plug as the valve at the back of the chamber. In total it has a length of over 6 feet (about 2 meters). With this larger cannon, I should be able to put an arrow into the barrel, and fire it at a target at the range and test the theory. The fins have about a 15-degree angle and with 8 fins will produce a lot of spin, in hopes to stabilize the arrow in flight. since the arrow will be pulled from the head rather than pushed from the tail, it should also reduce some of the arrows vibration as noticed by archers.
