So far, the compass cradle that held the spinner was rigid, so I could only tighten the bolts a bit before they restricted movement. I thought about ways to add an elastic component to keep continuous contact and eliminate the rattling. The solution was a top and bottom with cutting patterns that allowed flexibility.
Broken trials

I drafted several designs, from a simple spiral to a snaking spring. The purpose was to put as much linear distance between the hub and edge as possible but maintain enough strength to support itself. The snaking pattern proved to be the best balance between strength and flexibility. When I shook the compass, the rattling was gone, but I could not pick it up by the top bolt, or the spinner would dislodge.
