Phone Cradle for Xperia XA Ultra

I noticed a lack of Things for the Sony Xperia XA Ultra, and as I have one, decided to try my hand at designing something for it. I've used the Scosche mounts, but they don't like to stick to my VW Golf due to the texture in my car, and as this phone is just massive(164 x 79 x 8.4 mm ) without a case...it doesn't fit anywhere. This is my *hopeful* answer to my problems.
Simplify3d tells me it'll take 9 hours 19 minutes to print, which is a lie.
My machine took 12 hours, 4 minute to print this
