This design is the result of two years of revisions, and continues to evolve. The design process involved lots of trial and error: ordering a 3D print, seeing how the glove did or did not fit, and revising the 3D model. I also consulted models of the human skeleton, so that I could design proper joints and improve the overall geometry.
The current frame here fits me, a 5'9" average human male with somewhat slender fingers. In the future I hope to create a parametric model that can output gauntlets for people of other sizes.
