You can stick it on the side of your bed, on your wall or wherever you like :) iPhone can be charged while in the holder.
Made to fit with original apple silicone or leather cases, but it fits many other normally sized cases. It is meant to be attached to a surface with double-sided tape (strong enough to hold your phone of course).
Can be printed with no supports, but i advice to use them if you are not that sure about your printer. Print at 0.20 and use the variable layer height function for the curved sides.
