Please use OpenRedBird3D instead.
3D model for HKUST Redbird (Sundial)
Download the redbird2Print.stl or redbird2PrintX4.stl and print it with a 3D printer.
Follow the order of:
redbird.jpg => redbird.psd => redbird*.png => redbird*.3mf => redbird2Print*.stl
to create this 3D model from a photo taken by my phone because I did not find any specific parameters about the Redbird.
The colors are just to make parts distinguishable.
