Neato D7 repair - left over piece

[lastmile]

I've just finished disassembling and reassembling my D7 to clear out a huge amount of compressed lint that had collected under the back rear wheels to the point of jamming.

Everything is back together and running fine, but I have a small leftover rubber rectangle that fell out at some point when I was turning the D7 upside down.

Does anyone know where this part is supposed to go?

I only work with the older Neatos so I don't know a lot about the newer ones but I'm guessing it may go to the bumper or extra support for the wheels.

This is holding the cables going back to the Lidar, wheels and etc along the right side of the robot in place.
Basically, pushing them down. Nothing to worry about.
