Hi... while I'm putting together a video, here some pics of where I started from...

first some draft just to get into idea..

then I used a vector design software (idraw, corel draw, etc) to draw some parts, print on a piece of paper, and use it as mold to cut on balsawood... just to feel it in 3d.

once I decided witch parts would work better, I had it cut from a sheet of 2mm acrilic

some superglue.. spray paint, a microservo (and other for the wrist) and.. that's it. My U$15,00 hand...

Then.. I used the same method for the three fingers... except that I cut myself the first prototype (cause it's easy to cut 2mm acrylic).

and finally I came up with this design... I sent that to be laser cut (the fingers in 10mm and the other parts in 2mm)

here the laser cut parts. U$10 for four sets...
