The NZ Clinical Printing Group (NZ CPG) consists of a group of likeminded anaesthetists, ICU clinicians and others, who wish to collaborate on 3D printing projects for these fields. Their first project was to unify some of the CICO trainer designs they had created. This combines the best of a few models into one and includes an alternative larynx/trachea, so that blocked tracheostomy drills can be practiced. Referenced in several medical/anaesthetic journals and now available on Makerworld!
