This is a snap on case for the Samsung s8 Spigen Slim Armor case, so it can be worn around the neck.
The Fusion 360 file is also here, so anyone can modify the design. On the photos is the first version on the design. On the second version the tolerance of the joint between the parts is better and I add a lip on the upper part for easier removal.

I also added a version of the Vertical part without Mount so it can be remixed easier
