JB - I actually have a 3d printer as well as a large format laser cutter. I considered designing one that could be cut with the laser but I like the toughness of the metal ones. A nylon one cut out with the laser might not be a bad option though. One thing at a time! I'm trying to find a couple of people who are doing a lot of caponizing to try out my snare. I've got one on it's way out tomorrow and have talked to a couple of others.
