WE DID IT GUYS!! Our first successful test fire of a projectile (see GIF below)

We used magnetic iron PLA filament and a magnet to hold the 3d printed projectile in place and added external flutes to the OD of the projectile and it fired first try! We recorded our reaction right after in the video above (please ignore the cilantro in Katelyn's teeth that she's embarrassed about lol).
