These rails can be screwed on the underside of a shelf (or similar) to hang your wine, martini, liquor, or any other stemmed glass upside down under a shelf like in a restaurant.
Mount the rails spaced apart according to your specific glasses. Suitable for shelves with 200+ mm depth.
You'll need to print the included file twice. Once as is, and the second time mirrored!
