This modular servo casing allows you to use the same design/same part over and over again to create a robotic chain movement or loop. This allows for 2 degrees of freedom. I will be adding another axis in the future design.
There are two openings for servo wires, and a lid for covering the servos. You can chain up as many servos as you need for your projects with the same body design.
I included the source file, so you can close the holes or create new holes for the first and last modular for your robotic project.
