Build:

The cock cages have been printed with a 1.0mm hole through the hinge. In order to complete the cage use a pin vice or hand drill to drill a 1.0mm to 1.5mm hole through the hinge. The hole needs to be slightly larger than the pin used for the hinge. You can use a small nail for the pin, don't forget to remove the sharp point!
