I wanted a way to mount my iPhone 11 Pro Max (& case) to my Evolution Edge HD telescope; prefer to drive it that way. Also wanted to retain the Starsense keypad, as it's the best way to drive the focus motor accessory and make minor aiming adjustments.
The phone case is a Nomad, but other cases are similar size. If your phone is no more than 82mm wide x 14mm thick, it should fit. I also included a charger hole.
I printed this on my Ender 3 Pro, using 3D Fuel Pro PLA in midnight black.
Additional stuff you'll need: -VHB tape for the hand controller ring; I prefer 3M's RP family of tapes (RP45, 32, 16 mil, etc.) -Two 10-32x1.5" Thumb screws, such as McMaster-Carr part number 91185A390 -Two 10-32 square nuts, such as McMaster-Carr part number 94855A283
Enjoy!
