Printed 0.2mm, 3 walls, 15% infill. I did organic supports, support enforcers only and then painted on supports for the floating ring.
I printing in black ASA but any filament should work.
Fitting the phone mount onto the controller clip is a really tight fit so go slow and gentle. There might be some mild layer separation but it shouldn't matter as the phone mount retaining screws will pinch everything together again.
The author remixed this model.
The official phone mount's controller clip blocks access to sync, battery and power buttons.
Modified the original to be a little wider so as to accommodate the official phone mount as well as modified the rings for the same reason.
5-10 minutes in TinkerCAD and 2 not-quite-good-enough test prints later lead to the 3 one being perfect.
