The stand was made for an iPhone 7 plus, it supports its weight vertically and horizontally

i recommend that you drop in a key chain ring in the designated area after about 60% of the print its much easier than feeding the ring in later.

also i provided the SLDPRT if changes are needed to be done to the width of the phone.

EDIT: i edited the design a little bit, made it sleeker and made the keyhole in the back for convenience
