I made this for my phone, but it will probably fit many models. The cradle is 12 mm deep, 155 mm tall, and tilted back 15 degrees. The brackets are 50 mm apart, and there is about another 50 mm space under the phone so your charge cable has plenty of room to bend up to the socket.
This will probably hold together as press-fit, but some wood glue is cheap insurance.
I used a box generator web site to make the tabs, and Illustrator to make the rest of the shape.
One you have figured out some tabs and slots that work for your material of choice, it isn’t too much work to push them around and resize them. However, Fusion would probably be the smarter way to make something like this.
