Hello there again! Upon request and the fact I finally got the comments reenabled after almost a year, I was able to reach out to other builders who requested I make tutorial on the mechanical arm.

Step 2: Creating the Hand

Note: Regarding the strings, Quadruple knots are probably best as the constant pulling may cause a bit of unraveling. Face it, nobody wants to rethread the build after spending forever trying to get into the center chamber.
