I need to print a flexible, hollow "sleeve" or "cover" for an elongated part, kind of like a soft "skin" for a "finger" (see pic). I'm not sure how to approach the hollow space problem, i.e. how to print a flexible surface that is above an enclosed, hollow space. I could print supports inside, but they'd be hard to remove from inside the space, because I can't quite access all corners with a tool from outside. I could print this in 2 parts ("bottom" / "walls" + "ceiling" separately), but I'd prefer not to glue if I don't have to. Any ideas how to approach this?
