This is a handpicked list of phone case models I found on Thingiverse.com, Prusaprinters.org and other free sites, categorized by either being printable in flexible or other hard (PLA or similar) materials. The difference is that some of the cases are designed to be only for flex filament, otherwise you cannot strap them over your phone shell. Depending on the material you choose, you might have to slightly up or downsize the models to fit perfectly.
If you find other phone case models that are missing on this list, please send me a comment below, so I can add them here.
