It really does! I've got a voyager Nexus Prime and Scapel (with robot mode) in the works but those won't be ready for a looooong time..
Yeah! I designed it all using SketchUp. I have a few more products in the works but I don't have much spare time as of late. Loving your Galvatron btw, I mostly stick to 3d design but I'd like to branch off to customs like yours!
