D100 3D Shapes for Caves

Coming up with a list of easy-to-imagine caves to use in False Patrick and Scrap's upcoming Veins of the Earth spelunking-D&D book.

Most of these can be upright, inverted or sideways, of course, but I don't know how much those manipulations tax GMs' architectural imaginations in mid-game so I tried to keep the descriptions simple while still choosing shapes that translated easily to a describable negative space.
