Time to bring the Rhino models to life. I’m planning to fit a pair of them to a box and then move their heads with a cam or cams. I’ve put together a box of the size that I think would be appropriate.

A top view gives a better idea of how they are laid out.

I have made holes in the box ends for an axle so hopefully I’ll be able to retrospectively fit a cam shaft with cams and followers to test the model and see what the movement looks like.
