I created a remix of the icicle model (by faberdasher) and turned it into an ice dagger, which was used as a prop with lights inside of it. The default size of the dagger adjusts to an average hand size in the bottom part.

The prop is divided into three parts for easier printing, but the blender file is attached in case it is wanted to be modified. The middle section has both hollow and solid versions, so anyone can choose the printing format for using a light or other items inside of it.
