Tracheobronchial Tree Model

This learning supplement is designed to accompany the previously described bronchoscopy trainer. It supports recognition of bronchoscopy views and may be given to students as a compact 3D anatomy learning aid, as well as a desktop reference model.
The model used to create the bronchoscopy trainer, described earlier (https://sketchfab.com/3d-models/tracheobronchial-tree-d3cbd7d5adb74ba7b54c1df151900b96), was adapted for placement on a stand and includes numbered lung segment modifications. To improve print reliability, cubes were used to represent the 19 lung segments instead of spheres, which were difficult to print in mid-air even with well-calibrated printers. The model was reduced in size by 80% to facilitate handling and printing efficiency.
