Filament sensors do not need to be purchased, they are as simple using a end-stop switch to detect the presents of the filament, and a 3D printed case to enclose the switch.
My design is a little over the top, thou if you have the knowledge use it or loose it. I had fun making it and it turned out better than expected.
I Designed a case that was used to glue the switch circuit PCB into, and with a snap together case with a small hole for the LED makes for easy access.
