My 6 year old son wanted an android version of an Ipod Touch. I bought the LGL64VL from Walmart and just never registered it with Tracfone (i.e. no cell plan setup). Now it works great for him to listen to his audio books, and play games (that I approve through google play family link feature).
The phone case is designed to be printed in flexible filament. I used Esun eLastic TPE in yellow which prints very similar to original ninjaflex. But it would also work well in something like Sainsmart TPU which is more stiff.
