This was literally the first thing that I created when I got my new P1P!
It's a very simple shelf for my iPhone 11 to fit on to my laundry basket which is kept next to my bed so that I could see the time during the night.
I don't know how standard the holes are in my laundry basket, but they are 25mm square and 25mm apart, so it was easy enough to create the hooks for the support. The hooks themselves are a little deeper than necessary as it enabled me to add those small squidgy plastic dots that you can buy for putting under things to stop them scratching the tabletop, etc - don't know what they're properly called, sorry :-)
The author marked this model as their own original creation.
