Cable Disks

I used OnShape to CAD this 3D printed cable management system for CAN bus wires on our FRC drivetrain. These disks reduce slack, as well as protecting the wires from the swerve modules.

The biggest challenges in this design were the size constraints, as well as getting the tabs on the cover to flex enough to clamp onto the main body, without shattering the plastic. In terms of size, the disks had to be small enough to fit on top of our swerve modules and generally be convenient in terms of belly pan space efficiency, but they also had to fit our wire connectors, which are rectangular and do not curve.

The final version of the design is still a bit of a squeeze around the connectors, but is still a more convenient form of cable management than zip tied bundles, which could more easily get caught in the robot's mechanisms. The disks also have convenient channels that allow for zip tying directly to the robot.
