Sci-fi Planetary Defence Missile Turret [Support-Free]

This is a BIG print for those of you looking to keep your planetary settlements and outposts defended from any and all threats. As part of the upcoming Kickstarter I made a big-ass "planetary defense coil gun" as a request from a customer, and to augment the defenses I also added this "planetary defense missile turret". As you can see from the scale compared to a 1" based mini in the pic above, this is a larger model but it should scale up or down very well. It prints in 4 pieces, support-free of course, and the top rotates freely around the bottom.
