I remixed the model from Printables but here is the most original model for reference: https://www.thingiverse.com/thing:1012788
Feel free to adjust the width of the stand too so it fits your phone. 25mm worked for me, but 30-35 would also be good and slightly more stable. You can also make the silhouette itself slightly larger or smaller depending on the phone you have and the looks you are going for. You can do all these adjustments right in the slicer without any need for 3D modelling software.

Changed the tail length and made the model solid so the thickness of the outline can be adjusted directly in the slicer.
