Phone or tablet stand (adjustable)

A phone holder with adjustable inclination.  It firmly holds set position without needing to engage any locking mechanism.  Prints in place with no supports.  

The initial turn takes a little bit of extra force.  Do not over torque the adjustment knob, or you risk breaking it off.  Instead, insert an Allen wrench into any one of the 4 planet gears (see picture #5) and turn just a fraction until the mechanism breaks free.   It should move easily and freely using the adjustment knob at that point. 

Load as single object having multiple parts in slicer.  Test prints done in PLA, .2 layer height, 4 walls, 0 top and 0 bottom layers, 30% honeycomb infill, no supports or brim.

A second model is also provided, better sized for tablets.  See last photo for size comparison shot between models.
