Attached Link: SciFi 2106 one of my favorites from RMP

You can go the other way too... field effect hulls on a skeletal armature with crew modules, a drive and the field projectors.

I "made" a planet hopper ship by using BAR-CODE's drone as a drive unit and putting a projected field in front as the crew compartment.

Then there are organic models like the Lexx.

What has tied me up is making good handrails, hanger tracks, or gyro based aerosol propelled tow pods or spring bang sticks for maneuvering in zero-G. I have made the zero-G interiors by cludging interior compartments construction sets or in the case of coflek-gnorg stuff just flipping the scene.

Then of course I have wasted time trying to make gene-altered figures with upper and lower arms rather than arms and legs...
