It's something you can only due if your printer uses Pigment Ink, or you are willing to paint the parts afterward, which really adds depth, by the way. Start with a spoon, and make some blister, letting the excess paper hang off. The cut along the line you made and you will have your first compound curve out of paper, do it right, you can glue the halves together, and make either some kind of small spaceship, of your own making, or a blister pod, mounted on an aircraft or space ship. The possibilities are endless. You will need something to form the paper against. You can to negative, that is using the inside of a compound surface, like "DanBKing" did in his "Orion from 2001 A Space Odyssey", or positive, like using the top of a spoon or other object, and putting paper on top. You can also use glued wet laminated strips, applying the glue which won't stick to a stainless steel object, if wood, apply glue on top, let dry, then apply on bottom, for more strength, using it as filler, and sand lightly, then paint. This is one way of making flared fenders for older style cars, or making blister surfaces for aircraft, and anything else you can think of. Never try and make too much of a curve, you can always glue segments together.
You always learn something new everyday.
