I recently bought an iPad Pro, but without a keyboard/smart-cover I lacked a way to prop it up when using it as a video-player.
So I quickly whipped up a stand in Cinema4D.
Designed to print without rafts or supports on the Micro3D printer. I printed it in High quality to make the surface as smooth as possible.
No supports or rafts necessary. A little bit of sanding might be required to make the surfaces that touch the tablet as smooth as possible, but if you have a well-calibrated 3D printer this may not be needed.
