This is a second attempt to make a kit for my friend who had a stroke that make his left body paralyzed. He is recovering slowly during the last 2 years, and except the left arm, he can move his legs and can take care of himself.
This kit is to help him to open his palm, so that the muscle could learn a new palm-open stage. His palm can close but cannot open up. The kit is to give extra strength to keep his palm open - so he can learn how to move the muscle of the fingers.
The idea comes from the Aquahand by elerz92. Thank you for her beautiful design. http://www.thingiverse.com/thing:944296
The new design is for an easier print on Makerbot Replicator 2 which has a larger print bed size. This design also uses Silicone O-Ring as the tensioner instead of springs (as it is not easy to get the right springs).
If you want more tension on each finger, you can hook the o-ring to another hook and extend the o-ring length.
Be careful to select a good o-ring, and please check the o-ring to see if there are cracks before use. A broken o-ring could hurt other as well as yourself.
The material is PLA.
