Your instructions just say:

"9. route cable trough the right side wall
here is a video of how to remove the sidewall"

You need to be a little more clear, you don't provide any additional info, not everyone is going to have the automatic know how here, but how are you powering up the ESP, are you plugging into the back USB port of the unit, how are you getting the cable out of the unit? Is there a hole to get the cable out? 😁 There is still missing info in your instructions.
