Iphone Wireless Charger Mount

Designed a 3d printed iphone wireless magnetic charger for my desk riser. The max thickness you can insert this is less than 20mm. There is a screw that you can tighten to secure the mount to the riser so it wont move or come out. Once printed, insert the screw and use a coin to turn few rounds so that it will loosen up. PLEASE READ BEFORE PRINTING: This is only compatible for desk thickness that is less than 20mm.
