Elegoo Neptune 2 / 2S Filament Sensor Guide Hat

thingiverse

This is a filament sensor hat for the Elegoo Neptune 2 / 2S. I wanted to use a PTFE tube to align filament going into the runout sensor while ensuring it stayed in place during extrusion and retraction. Simply use a PC4-M10 pneumatic fitting to secure the hat and tube. "sensorhatcountersink" version has M3 countersink holes. "sensorhatsimple" version is just M3 straight holes (button or socket head bolts). I'll try measuring the bolt lengths I used previously and update this description, but I think they were slightly longer than 25mm.
