I've made a few small changes to the parts so that everything fits together better. Once done I printed out the bits, and put them together whilst watching Dr Who with #1 Daughter. 

The paper model is made from two separate modules. The Geneva Drive in one box and the Watt linkage in another. They are connected together with a drive pin. I've glued the two parts together then added a couple of elastic bands while the glue dries. The egg sits on the top. 

The egg is a little small for the box so I'm going to remake it 20% larger. After which I'll be fitting a dinosaur into place. 

This side view shows the Geneva Drive. The output from the lower drive shaft is connected to the Watt Linkage in the next  box.
