I wrote something on it for joke but I dunno how to remove it, sorry.
Anyway it's a good smartphone holder, i hope it's useful for you.
It needs a pencil/pen of the right size to work.
You can also glue the pencil to the piece for greater stability using hot glue.
I'm new to 3D modeling so the model isn't 100% perfect, I'm sorry.
Decrease the print density for avoid filament waste.
Have a nice day :D
