Gối đỡ bánh răng cho Adjustable Phone Stand (3D Servis)

A simple add on for the great Adjustable Phone Stand by 3D Servis.

This add-on just helps to prevent the gear moving laterally when turning the worm gear, as this can lead to skipping.

This model is pointless if you haven't already downloaded and printed the original https://www.printables.com/model/734305-adjustable-phone-stand and even then you may not need it.
