Spacers for Wine Glass Holder

The neck of my wine glass exceeds the width of the slot of this very nice wine glass holder so I made a spacer. It still discretely tucks up underneath the cabinet. It's 13mm so get that much longer of a wood screw to fasten this to whatever under-surface you're planning on hanging it from.
