I wanted to make some variants of these and ended up making some OpenSCAD scripts for each. You can specify the number and size of jaws and height (how much offset from the chuck face).

Some example output of the skeleton spiders are provided in .stl files.

Use the skeleton version with small width for narrow-diameter objects, and the other for wider disc-type objects.
