The Nabi Jr is a $100 Android tablet designed for toddlers -- a really great product (especially after a few additions in "Daddy Mode"). However, the accessory stands for it are not all that cheap and, frankly, have hinges that are not very toddler friendly. This is a solid one-piece stand that simply slips firmly over any of the mounting squares on the back -- allowing the Nabi Jr to sit nicely in many orientations and angles. Our 2-year-old "test subject" also found it to be a good handle for carrying the unit while watching it.
My first design, shown printed in black PLA, worked nicely but had a rounded edge with a little too much overhang to print smoothly. My second design, shown in white and posted here as an STL, has 45-degree beveled edges instead, and prints very nicely.
The white PLA print was made with 0.25mm and 25% fill, printed slightly hot to ensure good fusing. It took about 3/4 hour to print on our MakerGear M2. It is about as close to toddler-proof as I can imagine.
