Sound amp inserts

I printed thing:221284 as a gift, but the recipient didn’t like it that the iPhone SE flopped deeply down into the amplifier. So I made a holder for the iPhone so the screen can be seen and the controls are easy to get at. I made a second insert for an iPod Touch. Recipient has a Amazon Fire Phone that didn’t work well as a phone (hence the purchase of an iPhone) but still works to stream music over wifi, so I made a third insert for that. The photograph shows the amp with the Fire Phone.
