Stop the "spikes" from hard P's and T's! You'll need a 20 x 5 mm bolt and nut to fixate the "elbow". Some sanding may be neded for perfect fit at the elbow. A single layer thick nylon or a double layer of thin will do the trick. Strech and sandwich between the two circular parts. Mild force and at least four hands is helpful. O'yeah, you'll need a 1/4 inch bolt to attach the puff-protection to the H2n... Or you can just fit it between the H2n and your microphone stand.
