I found this little number on the hard disk of my desk top computer. I’ve tweaked the file a bit and made sure that everything works and uploaded it for your downloading pleasure.
Members can download the file (complete with instructions) for free. Non members can download it for a small free, or better yet, become a member and download this and loads of other paper projects.
The model uses a pair of cams working in opposite directions to move the cat back and forth in a haphazard sort of way. I hope you enjoy it. Have fun!
