In the movie Apollo 13, Marilyn Lovell (played by Kathleen Quinlan) listens to the NASA control room audio feed on a small speaker in her home. For the film they had repurposed a Tandy SP-150 speaker. This is a fairly accurate model of that speaker.

The screws I used to hold connect the back and feet are M3. The model is designed to use M3 x 6mm threaded inserts to secure the screws.

A wonderful job by spodokomodo.
