BTT Smart Filament Sensor Top Mount for Direct Drive Ender 3 v2

thingiverse

This is for Ender 3 v2 with direct drive setup. Filament sensor mounted on top next to the spool. May have issues if printing too high because filament sensor is stationary while hot end is moving, causing filament coming out of the sensor to bend. This may cause filament to bend sharply if hotend is too high. You will need to update filament runout distance to be pretty high because as the hotend moves left to right, it creates slack between the exit of the sensor and the start of the extruder. Filament will not move through the sensor until this slack is released through printing. I ran my wiring up through v slots behind v-snap covers https://www.thingiverse.com/thing:4641897 V slot snap on design comes from teachingtech's design https://www.thingiverse.com/thing:3223979
