Most companies won't design accessories for old products that have gone off the market. But I still love my iPad 1st Gen. So I designed a stand for it in the case.
The Apple wireless Bluetooth keyboard snaps into the stand. The iPad slides into the stand without removing the iPad cover, and can be used in portrait or landscape orientation.
The stand also fits my iPhone 4S in its Otter case.
The iPad Wireless Keyboard Stand has been successfully printed in PLA using my Tantillus http://www.tantillus.org/ RepRap printer. Slicing was done with Slic3r 0_8_2.
I have not attempted to print the part using ABS yet.
Note: Part dimensions will need to be modified to fit your particular iPad/case or other tablet.
