This is an add-on head for the Peak LED Solutions Vesuvius flashlight. The head accomplishes three things. 1) It prevents the flashlight from rolling when on a flat surface. 2) It allows it to head-stand with high stability. 3) It makes it much easier to turn the flashlight to full on (since this requires a lot of force). Due to 3d printing tolerances there will be a slight gap between the flashlight head and this add-on. You can use a small amount of conductive tape to make it a tight fit.
This is a travel comb I made for my wife and printed in stainless steel. I designed it with a tapered cross-section to give it maximum strength while minimizing material. I've printed it in both stainless steel and white strong and flexible.
