Risk Management Technical Imbalanced wells could cause vibration, wear and tear, and ultimately failure Insufficient RPM would yield inaccurate results Safety Piece of equipment could fly off while rotating Test tube could come loose while operating, causing sample contact with human skin Resources 3D printing resources could not be readily available Staying within budget Environmental/Social Device malfunction could result in incorrect diagnosis and possible infection Improper disposal of samples could result in biological waste hazards

Draft of Project Plan Objectives: Deliver a working prototype centrifuge which: Does not require electricity Is under 50 lbs Is adjustable for different tests and test tubes Compile a manual Gather together a lab kit: Initial Test tubes Microscope Recommended Next Steps (if needed)
