Rocker Clip Interest

There's a local company that makes 3d printed clips and pieces. Before I waste my time even investigating what it would cost to make a run of the rocker clips, I'm curious as to how many people are even interested. I'd hate to go to the effort, spend several hundred dollars, only sell 2 sets, and have the rest end up the attic for the rest of my life.

I mean, I still have brand new radiators that didn't move and the for sale section here shows almost no interest.
