Cheers but it looks like the whole chassis is bent. I've since noticed that there's a dent/crease protruding outwards on the underside, so a proper fix would mean an entire new unibody. Seems like it took a proper pounding. Probably a testament to the quality that it's still 100% functional. A lesser machine would probably have cracked it's Airfix chassis
I've decided I'll just leave it as it is and probably get a new one when they are updated. Especially if they make resolution upgrades to the next models, which they surely will.
