Great job, especially with your design decision to split it into two pieces. I found that the stand printed well at a normal infill amount of 10 %, but the holder required infill at 30 % to fill in the surface around the ridges properly. I added a rubber pad to the underside of the stand so that it wouldn't move so easily, but I'm considering changing that to reusable double-sided mounting strips so that family members don't move it at all. Thanks for sharing!
