Gravity-Tightening Phone Holder

A phone holder that self-locks based on the phone's gravity, offering robust support and a wide range of adjustable angles thanks to its spherical joint. Printed in one piece, with manually generated supports requiring no adjustment. The self-tightening structure is also integrated, requiring only one step for assembly – no instructions needed, simply refer to the finished product images for self-assembly. A small amount of glue can be used to reinforce the connection and assist with assembly. With sufficient print precision and minimal tolerances, it may even exhibit spring-back action through gravity.

Note: 1. After printing, if the self-tightening structure is too tightly bonded, separate the rack and pinion from the body by moving the two side arms. Do not forcefully pull the bottom of the rack, as this may cause breakage;

             2. Do not overtighten the spherical joint fixing screws to prevent the spherical joint from completely separating from the clasp.
