A phone stand that is hollow on the inside with a whole at the bottom, so you can fill it with sand for extra weight. That way the phone stand doesn't move when you put your phone onto it.

It leaves a space to connect your charging cable when the phone is in portrait position.

You can also use it to put your phone in landscape position.

Some minor tree supports are needed on the inside.

Printed in abs with 0.2 mm

Fill it from the bottom with sand and then glue the plug into the whole. It should fit nicely.

Optionally you can glue some felt feet at the bottom of the model for better positioning on the table.
