simple adjustable phone stand flat bottom rock holder

Adapted dav88's simple phone stand to have a flat bottom with no lip to better hold a slice of heavy petrified wood. I first printed in PLA but the teeth snapped. Using PETG they did not snap.

Single the rock is pretty heavy I might need to add a dab of glue to hold it better once I find the angle that looks best for the display.

They also hold chopsticks
