Robo Arm

thingiverse

When creating another invention I needed a arm to demo on, I thought about finding a person but then realized I could just print out an arm. That's when it hit me I just created a cheap prosthetic for 20$ now I know there's various challenges to overcome with prosthetics but this can help many people reduce large out of pocket cost for replacing prosthetics and also help children who generally outgrow their prosthetics quite quickly. You'll need to modify this to be compatible with your particular body type.
