Hollow parts?

Workshopshed

I was following a discussion on a blog about cable tidies and one of the comments got me thinking about 3D printing.

The idea is to have a hollow part and fill it with shot to make a heavier piece. I was wondering if there was anything specific that was needed in designing the part. I'm guessing that closing up the top won't be much of an issue as the filament will be partly supported by the content. I was wondering if the slicer would be ok with it and correctly hollow it or if it would try to fill it back in. I'll likely just use OpenSCAD.

    IMHO i would not leave anything upto the slicer. There are two ways about going into print for an object.

    1. For a hollow object, just split it in two and then shell both the halves. Then print them as separate objects. Make sure you add some notches to align the printed halves and then use super glue.

    2. For hollow grill like objects or the like, export an STL and then add supports in mesh mixer. It allows you to do supports, and all that stuff.
