Hi to all Flexi hand followers!!!
I printed this hand with a Rep 2. It came out perfect!!! ... almost no fixing necessary. For the joints i used Nylon 645 at 0% infill, works Great!!!! But i have two small changes i wish someone can make to this hand.
First, the idea of individual channels for each finger is great!!!. I think it will be better if those channels exits the palm as a circle instead of the actual lined-up configuration. Having those exits centered make the hand closer the the real hand (Carpal Tunnel) and makes it easier to make a wrist with movement for attaching it to a forearm.
Second, in another comment a guy asked for splitting the palm in parts to let the thumb one more degree of movement. I settle for fixing the thumb in a position that when flexed, it comes opposite of the index or middle finger, like a claw. That way keeps the hand close to the original design but enables to grasp round things like soda cans and glasses.
Thanks to gyrobot for this thing and to anyone that implements my suggestions.
