This is a stand for the Samsung S4. This old phone was repurposed as a dedicated Spotify music streamer. It was designed with the idea that it would always be plugged in to power and with an audio cable. The holder keeps the cables from moving or disconnecting.
You can download the A360, Fusion 360 file and modify the "tool" sketch to have it fit any phone you like.
