This is a screw on end cap for 30mm diameter stabilizer weights, with ¼ inch threads, and the slip on angled block gives a nice looking taper where the weight meets the stabilizer bar.

Fix a ¼ inch x 20 tpi nut into the recess with epoxy.  It the nut is too deep and sits proud, simply increse the height of the model in your slicer by a couple of millimeters.

These serve no practical purpose, other than to tidy up the appearance of the end of the stabilizer on my target bow.
