RE: A Bug! Answered
There is a bug on this page. I cannot use "enter" to go downward in lines. I tried. First, the site's page, https://www.instructables.com/id/Beer-Bottle-Lock/, has a bad download link in IE for the looking.stl file. I had to use Google Chrome to download the looking.stl file. The keep.stl file works on IE, though.
