Fiio M3 player shell for wearing on backpack

thingiverse

Using a player in a backpack can be really inconvenient, so why not move it outside? That's exactly what makes small players like Fiio M3 perfect for this situation! The wide clip allows you to wear it either on your belt or secure it to your backpack with ease. And if you prefer a more compact design, there's also the smaller no-clip version available. To complete the case, simply remove the supports and get ready to take your player on the go!
