Use M3X16 screws and M3-LOCK lock nuts to fix the acrylic panel and acrylic
washer as shown in the figure on the side panel. It should be noted that the lock nut
should not be tightened too tightly, because this is the rotating pair of the movable
part. After tightening, it will not be able to rotate and the servo will be blocked.
• Note: All lock nuts involved in this document should not be tightened.
