Flexible filament how to print a hollow "sleeve" 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?
Print orientation is usually the key to print with a minimum of supports. If you print this part with the sharp point down, you will get some support structures on the outside for overhang support to prevent it from tipping over, but no support on the inside.
