This is a stand to hold an Ikea Rallen Qi charger for an iPhone X or iPhone 8. The phone sits upright for easy viewing and this takes up less space than the charger would lying flat on a table. The RÄLLEN Charger is available at Ikea for about $12 in white or black.
It is designed so the phone will charge in either portrait or landscape mode, so you can charge while you watch a movie. It uses only the core Rallen charger, so you don't need any adhesives or the trim ring which comes with it. Keep the rubber ring on to hold the charger firmly in place. This is an easy print without needing any supports.
This should print fine with the bottom down.
