This is a handle similar to those included when buying an aquarium glass top. Sometimes these handles come broken or if you are making your own lid it is convenient to print them. You can use any method you prefer to attach them to the glass top but I use 3M Automotive Molding tape. You can find it here: https://www.amazon.com/3M-03615-Scotch-Mount-Molding-Tape/dp/B000BO9L00/ref=sr_1_1?dchild=1&keywords=3M%E2%84%A2+Super+Strength+Automotive+Molding+Tape+7%2F8%22+x+5%27&qid=1603044634&sr=8-1
