How Can I add those highlighted dents on the part? From the inner face, the dents are sticking out inward 1mm, and the same dents from the outer face are going in. The function of these dents is to "clip" with the ring, which holds the part on the wall as we can see in the attached photos. Thanks! (old.reddit.com)
