Matthias Wandel of woodgears.ca wrote in to share his Copy Carver project, with which he carved a telephone:

So far I had just copied a wrench with my copy carver, so I was looking for a more complex object to try. I had recently acquired a rotary dial phone, just for nostalgia’s sake at a yard sale. I figured this would be a neat shape to try.

I wasn’t sure if it was practical to do a good job of it, so I made a test carving of just part of the dial. That worked out well enough, so I went ahead.
