This is a replacement for a Sears Craftsman M13416A1 Tool Chest Drawer Catch. This fits onto the back of a tool box drawer, and holds it closed. It is used in many models of Sears Craftsman tool boxes.

I scanned a sample to get a .png with the top profile. I then cleaned it up, converted it to .svg with an online converter tool, and used Inkscape to convert it to a 3-D .scad model. Next, I edited the .scad to give it the correct scale and height. Finally, I generated a .stl with OpenSCAD.

PLA worked fine. I used 0.8mm wall thickness, and 10% infill, and it had the right amount of springiness.
