Several Groups in the Capital Region (e.g. UAlbany, Siena College, Shaker High School, Emma Willard) have chapters of eNABLE (enablingthetuture.org). eNABLE matches groups with the ability to 3D print and assemble hands and arms to people, especially children, with limb differences who can use these devices to improve their lives.
This meetup welcomes anyone interested in this topic, and in helping out. No previous expertise, technology, etc. is required. Just your curiosity and enthusiasm.
