I originally designed it for a Google Pixel 10 (Pro) (not XL) and an Ikea bed. I'm pretty sure it would work for other smartphones as well, as this model is intentionally loose to fit at least most of todays smartphones. For XL phones, you might want to scale it, but I can't say for sure.

It has spacings on the backside for the camera bar on both sides and slits to be able to connect the charging cable.

How to print:

Support is needed. Other than that, it's a pretty straightforward print. I used 15% infill. Smartphones aren't that heavy.
