iPad Mini Stand

One-piece iPad stand with two angles. Can be printed for iPad Pro (pictured) with 150mm diameter, or smaller iPads by changing the diameter.
The stand is parametric. Using the OpenSCAD file, can be printed on a MakerBot Mini, for use with an iPad Mini using 100mm diameter. Yes, Mini begets Mini! I hope mini people find this useful.
The OpenSCAD files are found here:https://github.com/thrasher/ipad-mini-stand
Write.scad found here:https://github.com/rohieb/Write.scadhttp://www.thingiverse.com/thing:16193/
Update: The inside-sphere writing has been removed in the .stl posted here.

Printer Brand:
MakerBot

Printer:
MakerBot Replicator Mini

Rafts:
Yes

Infill:
10%

Notes:
Use 3 shells to give the outside strength, and to allow the overhang in the middle of the sphere to print better. Note: the maximum build size of a MakerBot Mini is 10cm, which will work for holding an iPad Mini, or for 40 deg angles, a regular iPad Air. Use the OpenSCAD file to change these values, create a new .stl, and print.
How I Designed This
Originally designed to hold an iPad for my wife. She wanted to easily read, at a steeper angle than was provided by the iPad's case/cover. I wanted to support the iPad, but also other tablets, with or without covers. I also wanted to be able to add custom text, but on the inside of the sphere, so it wasn't overt. The Write.scad library works for this, though a little hack is needed for writing on the inside of a sphere.
