I am a big fan of the VR Headset by mikebattaglia and the VR iPhone adapter tray by ne14pez, and after upgrading to the iPhone 12 mini I realized I wa...s in need of a new adapter tray, so I whipped this up in Fusion 360.
The dimensions are fairly tight to the iPhone 12 mini, so you might accidentally hit buttons while trying to insert the iPhone into this tray. I recommend insert it at an angle, sleep button first.
I also added a little tab to make removing the tray easier.
Fusion 360 file included in case you want to remix it further.
