DS18B20 Mount

Simple DS18B20 temperature sensor mount based on the z endstop mount.


  • 1x DS18B20 / DS18B20-PAR
  • 1x 4.7kohm resistor
  • 2x M3x10 BHCS
  • 2x M3 nuts
  • 1x zip tie


  • Drill hole in rear panel for wires
  • Solder/connect sensor, wires, resistor and 4x2 dupont connector
  • Position sensor in hole
  • Bend sensor leads and secure with zip ties
  • Secure mount in place similarly to z endstop mount
  • Setup Raspberry PI for 1 wire (see https://www.circuitbasics.com/raspberry-pi-ds18b20-temperature-sensor-tutorial/ for a good tutorial)
  • Setup sensor in Klipper
    [temperature_sensor chamber]
    sensor_type: DS18B20
    sensor_mcu: rpi

Note: you can also position the mount on the inner side of the z axis rails which looks better, but also potentially block access to the z axis for later maintenance.
