Lizard knob

When the knob on my bathroom heater broke, I created a replacement knob and then realized I was an idiot. With a 3D printer I was no longer limited to the ordinary. I found a model I liked, added a cutout for a 1/4 inch D shaft and printed it out. My wife loves it. Please consider this more of a concept than a model, It works but the concept would work equally well for almost any 3D model.
