Think about how many of these you need to make, how quickly each one needs to be made, and how much you need to sell them for to break even.

Then think about how many you think you can possibly sell.

If you do the math, I don't think it's a viable investment to try to mass produce these, or even make them on a fairly large scale.

To actually make money you need to be injection molding, not milling these. Injection molding is orders of magnitude more expensive than even the most generous estimate of demand for these.

Given demand, and cost of contracting these out to a machine shop, or time involved in making them yourself, I don't think you can come out on top. Especially given that anyone with a manual mill or even drill press with x+y table can make one of these in about 15 minutes.

Keep in mind that if you choose to make them or have someone else machine them, you have to be able to meet the criteria of a vendor, as well as be capable to potentially ship one to every team in FIRST, if they ordered one, within x time period (I think 5-7 days? can't recall).
