I 3D-printed and assembled prosthetic hands through e-Nable, a volunteer organization that provides prosthetic hands to those in need, from open-sourced designs on Thingiverse.
This is the first prosthetic hand that I 3D printed and assembled. I found the designs and instructions from e-Nabling the future, a community of volunteers that designs, 3D prints, and assembles prosthetic hands for those in need.
I created the “Raptor Reloaded,” a hand designed for users with wrist functionality and a very good starter hand. I downloaded all the files from the “Raptor Reloaded from e-Nable” design on Thingiverse.
The print quality of the hand is nice and smooth, and the hand is functional (it can grip things) and looks like it should. The biggest flaw is that the elastic connecting the fingers to the palm is a little loose. Some of the fingers don’t snap back super well when bent forward because the elastic isn’t pulling on them tightly enough. This makes the hand’s grip weaker since the fingers can’t be controlled as easily when the hand is bent.
I’m currently printing another version of this hand on a larger scale (this one is pretty tiny) using the Ultimaker printer, which hopefully will make a smoother and cleaner print (and since the Ultimaker has two extruders, easier to dissolve supports). I’m hoping to send the assembled version of this hand to e-Nable for approval.
