Filament run out sensor to work with E3D / Clone Titan extruders.
UPDATE 3/19/2019:Made a few adjustments to the internal dimensions to accommodate the sensor properly and created a slot for the two bolts that secure the switch on the board. Now the whole piece sits completely flat on the bottom case.
Now everything seems to be working fine. Please provide feedback.
3x M3x16 screws
3x M3 nuts
25mm of PTFE tube to connect the sensor to the extruder.
NOTE: Leave some slack for the sensor to remain in place while the Z height increases.
Supports are needed to for countersunk holes for bolts and nuts. For lettering and arrow, use bridging settings in your slicer.
