BTT Smart filament sensor - Simple, easy print Ender 3/Neo/3v2 mount

BTT Filament sensor bracket for Ender Ender 3/Neo/3v2
by DAR01

This is a mounting bracket for a BIGTREETECH Smart Filament Sensor/Filament Break Detection Module to fit to an Ender 3/Neo/3v2 Printer adjacent to the extruder.

The bracket allows you to use the original OEM back cover of the popular BTT Smart filament sensor, and just replace the two middle screws with longer ones once the bracket is fitted rather than print a whole new back cover with bracket attached as many designs out there require.

This mount screws onto the extruder bracket (around the Z-Axis screw) and allows use of the PC4 bowden tube connector and short piece of bowden tube (that comes with the sensor) to guide the filament into the extruder arm filament hole, if required.

It requires x2 M3x8 Screws (the longer spare screws supplied with the sensor work well) to fit the mount to the back cover - Note: the original case screws are not always quite long enough to be re-used with this bracket. The bracket then uses the existing Z-axis screws to mount through onto the extruder bracket.

Note: Some of the attached photos show some earlier prototypes fitted on the machine (i.e. for illustration only). The stand alone photos on the green background are of this exact model as printed.

100% infill with flat bottom against build plate for best results.
