A friend of mine's father wanted some guards/pads for his set of harbor freight clamps. Instead of just the clamping part, he wanted them full throat depth to ensure it remains square. These are what I came up with. They simply click on, and when printed with an 0.6mm nozzle @ 0.4 layers, takes a little over an hour to print (3 perimeters, 30% infill).  Turn the smaller piece so the opening is down and you shouldn't need supports. I've also included gcode for the MK3S+.
