Armor case 3D design for Smartphone

Case Design

Hello, There are 4 parts to this case in a sandwich stack format. All the wiring is concealed. The top and bottom layers hold all the parts together with 4 screws. I also made a port for external charging and two holes at the top to be able to hang it to the neck with a lanyard just like you mentioned. The inner tray is made of textured plastic to provide better grip on the phone. I can provide the file for manufacturing as well. Do let me know if you need anything changed. Thanks
