Zeiss VR One Plus Centering Helper Tool for iPhone 6, 6s, and 7

The Zeiss VR One Plus is a nice VR/AR headset for mobile phones and the successor to the Zeiss VR One. It eliminates the need for specific trays used with each mobile phone you want to put into it, like it was with the Zeiss VR One. But a disadvantage is, compared to its predecessor, that the mobile phone is not as easily centered into its new multi-tray. This tool basically is a frame for your iPhone (6, 6s or 7) and helps you with centering it into the multi-tray.
