MP3 Player Holster

I bought an off brand MP3 player for another project I was working on but decided not to use it there. I started using the MP3 player the other day and found that it sounded pretty good. The only issue was when I had it in my pocket and while working and moving around, i would sometimes inadvertently press the buttons so I decided to make a holster for the player.

The MP3 Player is this model: https://www.amazon.com/gp/product/B073R7ZHVC/ref=oh_aui_detailpage_o09_s00?ie=UTF8&psc=1

When slicing, rotate the holster so that the flat opening (top) is down on the bed and use supports. I included pics from my slicer to illustrate what I mean here.
