Pretty impressed how well that one turned out. Used SUNLU TPU in yellow with 200/50 degrees Celsius at 20mm/s speed on my Voxelab Aquila (upgraded PEI bed and DirectDrive, also used Filament drybox).
This filament to be exact:

How drop resistant is it? I drop my phone multiple times daily, face first, on the side, on back, corners, etc.
If you drop I that often I probably wouldn’t use this model and since it came off the printer yesterday evening I unfortunately can’t tell you how resistant it will be. It’s for my wife’s phone, she doesn’t drop it much, it’s gonna be more to protect the phone against other things in her purse.
But maybe this model is something for you:

If you drop your phone that much, I think this is the case you need: https://a.co/d/1fyszgF
