So I took the only bit of Wolf-E I didn't mess up, the motor mounts. The Idea is to see if the ESCs would be able to fit behind the motors and looks promising. Yes I realised I plugged the motor into the ESC's power cables when I took the picture



I also took a second go at the threaded bar, this time with better results, the holes might be a bit wonky but at least I didn't break anything this time.
