Robotic Hand

Slight remix of the Robotic Hand v3.0 by Juan Gutierrez. So, for the most of the details see [original project](https://www.thingiverse.com/thing:14986).

In this version I:
- changed thumb position and shape so it represents human hand in relaxed position
- added more material to the finger joints so that fingers are a bit closed in open position (if you look at a finger from a side it is no longer a straight line, but a curved line, like a bracket "(" )
- added round corner for a string tunnel inside palm base, I thought it will make it easier for my printer to print (eventually this looks like a redundant measure, as it prints just fine without that)


For those who happen to live in Russia and have no Idea where to get those rubber bands, you can get those in orthodontic shops, they are 1/4” in diameter. In Russian they are called "эластики" or "ортодонтические резинки" or "резиновые тяги", they also have names for different hardnesses, I got "Медведь" 1/4, 4,5oz (strong),
