This mount places the filament sensor at the center so that it can be used with either of the two spools.
It was designed to be compatible with the LED panel of the Elegoo Neptune 3 Pro.

You will need three M3 screws:

• [1×] M3×9 mm
• [2×] M3×16 mm*

*) The screws should go all the way in and sit tightly while leaving the sensor mount space to move around them. This is necessary to compensate for quick upward movements, e.g., when the filament is retracted or when the print head moves up after printing has finished.

If you like this design, please consider leaving a ♥️heart. Thanks!

This is a refined version of my original model.

So what makes it better?

• Sturdier: increased durability
• Places the sensor higher: reduces strain on the filament when printing high objects or when the print head elevates after a print has finished
• Model already comes in print orientation: no manual re-orientation in the slicer necessary
• Prints without support: easy printing
• Prints even faster
