Magnetizing the large turret in such a way that (hopefully) if I ever get the upgrade pack, I’ll be able to just snap the new gun right into it. There’s a lot of magnets here.
The side (left) has a magnetized strut for holding the hatch option on the top. This is glued to the inside of the curved wall, and has a shelf on the other end to help glue it onto the back wall when the whole thing goes together.
The gun mount is magnetized, and the gun has the two lugs cut off and drilled out to fit magnets in.
The magnets on the front piece allow me to remove it to swap the guns, and (hopefully) to be able to swap it with the more open front from the upgrade pack.
I also magnetized the periscope, with just a magnet on the bottom. It attaches inside on a magnet on top of a stick of styrene.
