These are calibration 3-D model STLs used for the study 360 Degree Real-time Monitoring of 3-D Printing Using Computer Analysis of Two Camera Views. In addition, the STL and SCAD code is given for a first generation 3d printable design to attach the cameras to the MOST delta. Models used for the following paper: Nuchitprasitchai, S., Roggemann, M. & Pearce, J.M.
