Started soldering and arranging all the cables. I also went with velcro for securing the battery which was a great tip I got from Radomir Dopieralski, thanks!

I am quite meticulous with the isolation of the wires since I do not want this robot to be a fire hazard caused by loose wires.

The header to the left is double three pin version with ground to the right, 5v in the middle and the signal cables for the servos on the left.

Cable management in the upper part, only the signal cables for the servos in the bottom should be needed since the header in the bottom shares the same ground and 5v output.

Attached a on-off switch which is connectod to the enable and ground pin of the powerboost which makes it possible to completely turn off the powersupply.

As Ben Heck often says, make things that you can take apart. So I have soldered removable header pins to almost all parts of the robot.
