Tevo Tarantula Filament Runout Sensor Enclosure

3D model description

I designed this to be used with the spare sensor that comes with the Tevo Tarantula kit. You can either use small screws (M2) to attach the switch, or as I do here, simply use 1.75mm filament to attach the switch to the enclosure. Screw the enclosure together with 3 M3 x 12mm screws and nuts. I used some short pieces of PTFE tubing on the ends of the enclosure, but this is by no means necessary.

Print the filament_runout_enclosure.stl twice. After printing you may want to sand the pieces down, so the fit together nice and flush.

I used the Z+ Port, therefore you need to set FIL_RUNOUT_PIN in pins_RAMPS.h to 19:

 FIL_RUNOUT_PIN          19

In Configuration.h search for the FILAMENT_RUNOUT_SENSOR define and comment it out. If you want to use the default pinout, also invert the logic of the sensor and disable the internal pullup:

 FIL_RUNOUT_INVERTING true // set to true to invert the logic of the sensor.
  //  #define
 ENDSTOPPULLUP_FIL_RUNOUT // Uncomment to use internal pullup for 
filament runout pins if the sensor is defined.

More information about the Marlin configuration can be found here.

OpenSCAD file is attached and may be customized via Customizer in case you want to adapt it for a different switch, or your tolerances.
