A new project useful for both mechanical experiments both as an attempt to create a prosthetic aid at low cost.Unfortunately not everything works correctly, and much depends on the PLA FLEX you will use for the part of the fingers. It should be one of your intervention to improve the elastic response and the return of the fingers in position 'open'. Not a project working perfectly but you can use it as a starting point for your other projects.Soon we will have new developments of the project but for now try to use as much as possible of what we publish.
