I think for your RWRA2 robots, you might have to make a separate showcase in the Custom Components sub-forum. Speaking of which, that looks like an RWRA2 build to me. Either way, you'll want to get some supports on the weapon. The real Cedric Slammer had a structure on the left-hand side of the disc to hold it in place. Even if this wasn't a replica, it wouldn't be IRL with the disc just floating in mid-air like that.
