Do you want to charge your phone, but there is no table nearby? This allows you to put a shelf on the outlet with your charger. Since it is flat (until you fold it), it is easy to pack in your luggage. The print is quick and uses very little plastic so if you leave it in the hotel room, it's no big deal. To use it, simply fold it and put your charger through the plug holes. I printed it with a 0.4 mm nozzle and 0.2 mm layer height. Many thanks to DesignMakeTeach who gave me the idea for foldable designs.
