Tube Roller

Hi this is George, in my engineering class I made a 3D CAD model of a tube roller. For those of you who don't know, CAD stands for computer-aided design. This

is the use of computer systems to assist in the creation, modification analysis or optimization of a design. The tube roller was designed and built by my classmates, Jonathan and Diego.

What is a Tube Roller you ask?  A Tube Roller is... a machine with three concave rollers. The tube roller example below is one made by the Harbor Freight company.
