Three knee hub

thingiverse

This is a custom air vent designed specifically for ski boot dryers, perfect for use in caravans. The knee plug fits securely into the hot air outlet. For durability, use heat-resistant printing materials to create the part. To enhance its temperature resistance, I applied a layer of fiber-glass over its surface. Check out the image to see how it's used. If you find this design helpful, consider supporting me with a coffee: https://ko-fi.com/pistaj
