Thanks a lot to Sergei for the original design and also uploading the f3d file, which made the remix super easy!
Prints well standing up, for the round part you could add a tree support, but it is not necessary. I didn't use a brim on my textured PEI plate.
PLA holds up nicely in my case.
The author remixed this model.
The original uses a top and a bottom part to fix the iPad to the wall safely. I enlarged the bottom part and added little side-holders so the top is not needed anymore
