v2 ^^^ Doesn't fit on my arm - but you get the idea. The shape here is slightly different than that of v3. I like the way this one feels on my own arm better than the second version - it is more comfortable around the wrist - but that could be because it's just slightly wider.

v3 ^^^ This version goes around the arm a bit more, has a slightly different profile near the wrist, and a more developed surface pattern. I think the surface and form is more successful on this version than in v2, but there still needs to be some refinement in the functional parts.

Before I do v4, I am going to attempt to make palm/hand v2 using the same process.
