iPad stands for videoconferencing

One design is more conventional: a vertical wall and several slots for the base, giving very diverse angles. The other design has five slots all of different labelled widths, intended to support slightly different angles. The narrower version was tuned to accommodate standard iPad Smart Covers; the wider one, for chunky kid-protecting covers. It should be easy to adjust to other thicknesses and sizes by changing the parameters in the OpenSCAD file.
