I don't like traditional flip folders for iPads, which means I have to resort to a dedicated stand if I want to use my iPad as a second screen on my Mac. The issue with many of the printable stands I've found online is that they're too small or flimsy to hold the larger iPads, especially if you need to interact with it.

I've designed something that's perfect for my use case. I can use it in landscape mode without issue, but it's also sturdy enough to use in portrait mode. I've even added an opening in the centre of the stand to allow access to the USB port when in portrait mode.

I've also added some additional thickness for when your iPad has a case or folder, to still fit properly.

Provided your printer is tuned properly and you take it slow, you won't need any supports for the overhangs.
