DS18B20 Mount
Simple DS18B20 temperature sensor mount based on the z endstop mount.
BOM
1x DS18B20 / DS18B20-PAR
1x 4.7kohm resistor
2x M3x10 BHCS
2x M3 nuts
1x zip tie
Instructions
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
serial_no:
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.
