My mom loves this phone, she dislikes the store bought masks cause they're too clunky. The case seen on the images is printed on an Ender 3 v2, with Verbatim Green ABS.
Print suggestions:
Suggested Material: ABS, PLA or PETG,
Nozzle: 0.4mm
Parameters/infill: at least 4 params, with at least 20%. You could go higher or print 100% infill for a more sturdy print
Layer height: 0.2mm works fine
Supports: The “Organic” mode, auto-generated ones from PrusaSlicer work just fine.
