Creator's description
My Patreon supporters get this model free! :) Update: Now includes separated STL files for multimaterial! planetary-phone-stand.stl is the single material version, while all the others are the components that make it up (but are still intended to be printed in place together, assembled) Do you need an overly-complicated way to prop your phone up, one that says to everyone around you that you have a 3D printer? Then this is the model for you! The angle of the stand adjusts by pivoting on a set of planetary gears, and is then fixed in place by tightening a sliding bolt form the opposing side.

How to print
This is an articulated print, so make sure your bottom layer is nice and neat, and that you don't have any printing issues like overextrusion or stringing that might bind moving parts together!
