SN04 Sensor mount for Ender-4

thingiverse

This is a device for mounting the SN04 sensor for the ender 4. I used a 10-32 bolt and made it into a Tbolt. The 10-32 will provide enough resolution, so that 1/12 turn will give you .003" (.06mm) movement. You can use a double hex nut and put a mark on it for better control of the displacement. I printed mine slower to get better resolution, the tolerances are tight so you may have to do some sanding. I used a piece of sand paper for the final touch. This will reduce backlash on the part and allow you to have better sliding and no unwanted movement on the sensor.
