Make up mirror hinge

Mother bought a makeup mirror that was directly attached to it's vertical stand which does not have any adjustments. The vertical stand post is 20mm diameter and this hinge fits the original cutout for the mirror. The hinge allows for adjustment from 0 to 30 degrees of tilt for the mirror. It also allows the mirror to be installed rotated 180 degrees so that the mirror is closer to the desk and has really low centre of gravity (requires extra hole at the back of the mirror) Onshape model here: https://cad.onshape.com/documents/2f94b6ed5dbd3727c7260179/w/3b81b6bb52943458e4bb9131/e/c7b7de3d049b9efa55c0e34e?renderMode=0&uiState=69877abc43407a0a82531c58 Installation requires:1 * m3 nyloc nut to be pressed into its recess 1 * m3 16mm screw (cap head)2 * similar wood screws that the stand already has for its original mounting
