The document describes the design of an improved medical tube for dispensing expensive eye medication. It discusses current tube designs and their limitations, and proposes a new "ecoTUBE" design with a plunger that can more accurately dispense all of the medication to reduce waste. The ecoTUBE design was selected through evaluation criteria and 3D printed prototypes were created and tested. The document outlines the ecoTUBE design, materials, manufacturing process, and cost analysis, concluding it is a more user-friendly and economical solution.
