I broke the original case latch and couldn't glue it back together because the material is only 2 mm thick at the break point and the load causes it to tear.
So I made a 3D model of this clip with greater thickness.
Printing is simple, print standing up, on the side with the finger rest, turn on the skirt if you have adhesion problems.
A 15% infill works for me, it hasn't broken yet.
Good luck!

p.s.
There is only one model, as the clip fits both sides of the case, so you DO NOT NEED to mirror the clip to print the second one.
