Hello, we are building projectbiped.com's "ROFI". To power the robot's 12 servo's the architects advise to use two IDC style male-male 90* elbow headers (6x3pins). One row of pins plugs into the board's data pins, and they then advise to solder the next rows with positive and negative leads. What a booger to solder!
So my question became: Are there creative ways to create some header sockets, off-the-shelf or 3d printed that can split the signal of one power wire over 12 idc style pins?
That and we probably could use some soldering help if the former doesn't fruition.
Thank you
Twelve servos it a lot. You will struggle to get sufficient current to drive them all from most power supplies. You will also need to add some hefty decoupling to each of the power supplies, I would use a pi circuit for each power output, like the last one on this lisnk:-

Ok then the answer to this is to take up knitting and forget all about electronics, if that small amount of soldering puts you off then this is not the hobby for you.
Thanks for the non sequitur and encouragement grumpy.
My students and I have been working on soldering this step for hours. Let me know how you faired on your rofi....
Anyways I'm looking for technical solutions or products.

You can slightly bend hookup wire (or individual cat3 telephone wires) and stick into the servo connector. A drop of hot glue will hold the wires to the servo connector. The other end of all the power wires can be soldered together to a main power wire. Same for the servo grounds. The control signal wires use a terminal strip like below. The arduino header pin spacing may be different from most header spacing.
