This is the very first thing I designed and made from scratch. (I just started 3D printing a week ago)

The phone stand keeps the phone at 30 degree angle. I wanted a phone stand that would keep my phone more vertically rather than inclined. 
The hole has a sung fit for a standard USB C connector when it's charging the phone so if you have a fancy USB cable with a longer sleeve, it won't fit

I printed it 0.20 layer and 20% infill on its side with tree supports for the hole with PLA on an Ender 3 v2 NEO. It's sturdy and has a certain springiness to it, but nothing you'd mind. The phone sits perfectly. I really don't know if it would work without supports.

Hope you guys find it useful as well as pretty. It was fun making it.
