Filament sensor holder for FLSUN QQ-S

thingiverse

This adapter enables both vertical and horizontal movement of the sensor, ensuring it orients correctly regardless of whether the filament originates from one side of the coil or the other, as well as when there is a large amount of filament or very little left. It is secured to the base using double-sided tape, with the ideal placement clearly visible in the accompanying photographs. The sensor is stabilized solely by an M3 screw through its bottom hole. With a layer thickness of 0.15mm, it prints well and moves smoothly. It's designed specifically for the most widely available sensors found on Aliexpress. Be cautious when connecting the sensor to the board, as the pinout may require adjustment. Double-check before proceeding, as you might need to swap the "V" (red) and "S" (white) wires in the plug to ensure correct alignment. If necessary, it's easy to remove the pins and reinsert them into their proper positions.
