I have an STL file for a battery box. It consists of a bottom and a top part, that are connected with a simple hinch. On the other side the box is being closed with a latch, see blue circle in image. The problem is that this latch is breaking off because it is not sturdy enough or the tolerances are just too tight so you have to apply too much force to open the box. Please send an STL and ideally a step file that fixes this problem. This is for 3D printing with FDM printer. For an experienced designer this should be quite easy, I think.
