Tracheobronchial tree model for bronchoscopy training. This model has luer lock (IV) connectors at 8 different locations at the end of 3rd generation bronchi. This allows a syringe or tubing to be attached to make this a bleeding model for the identification of different sources of bleeding. Please note that these are sealed. To enable bleeding, you can drill or poke a hole in the membrane to open the lumen. 

This version is made for TPU to allow some flexibility. Adjusting the number of wall loops from 3 to 2 will make the model more flexible, but will reduce the quality of the fine details on the luer connectors. This model can also be printed in PLA or TPU. PLA will be very fragile at this wall thickness.
