This seems plausible. I wonder if they could identity any particulate from the fibers around the knobs that might corroborate this. On the wikipedia page there

This seems plausible. I wonder if they could identity any particulate from the fibers around the knobs that might corroborate this. On the wikipedia page there is an icosahedron pictured next to these that does not have finger size holes but I suppose that could be unrelated to this artifact's purpose.
