This fingertip is based on a silicone fingertip which is used by a research group in Brazil (mao3d) for e-nable (enablingthefuture.org) prosthetic hands. I intend to contribute to the project and this is my first prototype using flexible filament (Ninjaflex) to print. Printed with 0.1mm layer height using 30mm/s speed and support in the hollow circles which was later removed. It will pass through some tests and will likely have a few iterations because it's good enough for replacing the silicone part. I have modeled it in OpenSCAD to enable others to improve on my design and also to be easily modifiable to various sizes. In the future, I will probably turn it into a custom or parametric design. Kudos to Dr. Maria Elizete Kunkel who gave me a sample on which to base and model the part.
