I wanted an owl clock with moving eyes, so I designed one.

I used this ring model as my base design

You will need a battery powered clock with a pendulum 

( or just glue the eyes in place for a clock without a pendulum)

This model is sized for a clock with a minute hand measuring 53mm

I tried uploading a .3df file showing all the pieces in place and colour coded, but it's not a format that's accepted.

Post Script: It was brought to my attention that some people had problems printing this model, so I uploaded a repaired version labelled "Owl Clock revised"
