This is a project was done with a student as part of a class that I conducted which dealt with the principles of FDM 3D Printing.
This project was an exploration in functional 3D Printing to design an object keeping in mind the limitations of the medium. Some basic ergonomic studies were conducted to finalise the frame dimensions, next the joints were modeled in Autodesk Fusion 360. Following this the parts were then printed with a homebuilt RepRap printer. Thick PVC pipes were used to create the frame.
