Print the model, insert the 3.5 inch floppy disk and use it as a phone stand.

Floppy is not included, dig your own somewhere in the attic or print 
a “save icon” like this one: [https://www.printables.com/model/510115-35-floppy-disk](https://www.printables.com/model/510115-35-floppy-disk)

The disk slot is thin enough to hold the diskette tight, so it's may be a bit harder to insert a 3d-printed “floppy disk" than a genuine diskette.

Phone shelf is wide enough to hold even a thick extreme phone case.

Any filament, no supports.

I printed it on Bambu P1P with Spectrum PCTG Premium filament, 0.25mm layer height. Accidentally added a brim, but it's not needed.
