Octoprint HomeAssistant ESPHome Filament Sensor for Ender 3

I wanted a fiament guide that included a filament sensor. But, I wanted it to interact with my HomeAssistant / Octoprint setup so I could get notifications via HA and get better control. Also my raspberry pi isn't that close to my printer and would have needed long cables running back to it. 

I remixed the two parts to combine them. I've added a 24V - 5V USB power supply and power my ESP and LEDs via this.  

This is v2 of the remix to improve filament pass through at the exit and some reliefs for pins on the wemos.

Excuse the poor print - I'm using up some PETG which isn't of the best quality.  

I did have to run an M6 bolt down to thread for the Bowden connector. I was printing with a 0.6mm nozzle and struggled with the thread with the PETG I was using.
