Ok, finally had time to polish up and post the direction I am going in. Still not done and pretty rough around the edges but moving in the right direction. I am having a hell of a time with the rotating hard suit joints - The geometries involved are unlike anything I've had to draft out before so there is some drift between joints and views that I need to hammer out. It would be really fun to see animated but it is not easy to design while keeping it cool.
For the final presentation I will also be including a figure wrapped in the white micrometeorite armor mentioned in the book so I've been adding small electro magnet pads to the suits to anchor those in place.
The various waste and fuel tubes are not really well realized and I may need to just treat them as something that require a teammate to change out due to their placement.
