This is a basement for my NFC Deck keypad to hold the NFC cards close to it that are used. This can be for an NFC powered movie or music system, or any other use of the NFC tags in Home Assistant automations. It should be printed vertically with the opening facing up, without supports. To prevent the NFC reader from picking up the NFC tags in the basement, I glue sticked on a small piece of tin foil. Hot glue would also work for this, just don't burn yourself.
