If the topic of custom or DIY prosthetics interests you, please get involved! A great place to start is e-NABLE, at http://enablingthefuture.org, where Jen, Owen and team are doing fantastic work to bring volunteers and contributors together with those in need.
Most of e-NABLE’s work has been with hands, they now have many designs to best fit the creator and the need. They have also featured our design for those with finger needs.
Here you can also find an article with an interview on knick and his design: http://enablingthefuture.org/2016/05/02/knickfinger/
