This is designed to be a drop-in replacement belt clip for a well known name brand radio. It has most aspects of the original - including the overall curve and retaining stops underneath. You need to print this sideways (on it's side) to get the required bending strength. I printed in black ABS (and white) and the part happily bends at least as much as the original without snapping. Photo shows 2 3d prints (lower) and 2 originals (upper, one snapped). Dont forget to print this on its long side for bending strength.
