Theres a open source sensor by INFIDEL which i would like to implement due to its ease to make a manufacture.

[TeslaMaker]

can you please provide some help to implement that sensor in your firmware?
Is you sensor used in a closed loop control or is it just for monitoring the diameter?
link to the sensor im talking about : https://www.youmagine.com/designs/filament-diameter-sensor
link to the firmware for the sensor: https://github.com/drspangle/infidel-sensor
InFiDEL - Inline Filament Diameter Estimator (lowcost)
this sensor outputs data via i2c

I looked into it and it seems that it should be possible to use the INFIDEL sensor as is, The release version of the infidel firmware supports analog input on it's pin 5. The analog input should be compatible with the default filament sensor setting in the Makrel firmware.
