About this 3D model

Hello, I'm a 16 year old boy and I love designing all sorts of things. Recently I've been wanting to become a biomedical engineer who designs prosthetics. This was the perfect opportunity to get me going on my journey. Throughout my design process I decided I was going for flexible fingers with a superficially rigid palm and fourarm. Then came the designing. I believe getting the angles on the fingers was the hardest part. The fact that I had to angle them to function at a certain point was trickey. I went through multiple designs until I got it as close as I could. Then came the palm. Since the design came from the measurements I took on my hand I knew one of the harder designs was going to involve my hand. Until I remembered a video I watched where photogrammetry was used to scan a house. I then scanned my hand then hollowed it out, made it lower poly, then in a different software I added finger holes. Then came the saddest part. Electronics. I was not able to attain the electronics needed to make the arm/hand portable (how I wanted). I really wanted to do so many things with it. Nevertheless, I came up with a simple solution using k'nex and my dad's electric drill. By making a stand for the hand out of k'nex, I made an axle and then connected the filament inside the fingers to a servo like grip. Then I connnected the drill and tightened it up. It worked, so that made me happy. A few things I forgot to mention: The Fingers move because filament or some kind of string is connected at the top of the finger(s) running down through all of the holes. All parts are major parts are 3D penned or glued into place. Most parts will require support when printing The wrist snaps back into place when moved because a rubber band connected to Top Wrist.stl and runs down the F-arm. Coolio :)
