I design and build unique items for modern and vintage camping and household stoves. Most notably, I am the original designer of silent burner caps for modern backpacking and camping stoves. I am known as "BernieDawg" throughout much of the internet outdoors and vintage stove collection community. I am now releasing my legacy designs and making them available for direct sale from the 3D printing manufacturers. I don't make a dime off these sales. In fact, I make about 5¢ per sale. Here is a great opportunity for you to get these great silent burner caps at the same price as I've been paying - direct from the manufacturer - plus five cents.
