Replacement frame of OxyLED HL-02 headlamp

The Chinese-made OxyLED HL-02 headlamp previously sold on Amazon was an amazingly good value. My two are still going strong after eight years of regular use. The weak point is the frame holding the body of the headlamp to the strap. This is a replacement of the frame. I've included the OpenSCAD source code in case anybody wants to improve on it. I found that tree/organic supports to be superior for this model.
