The lower hull is pretty heavy, so it should crawl around nicely. The upper hull is all 3D printed so it is as light as a feather.
I sometimes feel guilty because instead of cutting up styrene and gluing it together, I am designing parts on a pc screen, loading them on to the printer...and going to bed. I wake up the next morning and all of the hard work is done for me.

I have learnt how to design parts with all of the hatches and mouldings in one piece, so this whole build is very few parts. It saves print time, filament, and of course everything is perfectly positioned and aligned, with no gaps to infill, which makes everything nice and clean. The whole design is less than 400 lines of Openscad code, which is quite amazing really.
The rear deck reprinted, and clears the gearboxes. Just started the citadel, which is a 22 hour print....
