Clever way to create snap fits for 3D-Printed parts

thingiverse

I often see people strugle with snap fits on 3D-Printed parts, as the layers seperate very easy under bending forces. Some time ago I ran into the same Problem and came up with this solution, as you can see it in the center of this part. A small PCB had to be hold down, but snaps in Z-Direction constantly broke of. So I changed the Design sothat the bending elements are to the sides and follow the 3D-Printing parts. This makes the snap mechanism very flexible but still tough. Maybe I will create a better part to show the principle, but this is what I had on hand and I just wanted to share this trick with you.
