Anet A8 SN04-N Auto Leveling Sensor Bracket w slidable cutout

thingiverse

This is a small rework of https://www.thingiverse.com/thing:2063521 Changes: - Modified through hole for sensor cable to side-slide for easier access (preventing need to remove all wiring for probe if switching bracket) - Mounting hole converted to slidable cutout (increasing range for probe to be mounted on, avoiding proximity issues with surface) To connect SN04-N probe, optocoupler method is used to supply recommended voltage for better sensing. A 4N25 optocoupler (4N35 etc., under $1) is employed with a 1K resistor. Alternative method using 1N4148 diode also works fine. Default setup did not work via 5V S_Z, as probe's LED did not turn on when touched with metal object. However, some users have reported success. Remember: Avoid over-tightening zip ties to prevent cable damage.
