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

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.
