With hearing aids part of the (very expensive) all-inclusive packet is - besides the hearing aids themselves and the endless sessions to fine-tune them - an actual mold of your ears.
At least last time i saw the procedure the "take the mold" part could well be a DIY job, you have two small bags of (silicon/resin/whatever) A+B, you mix them together in your fingers into a small putty-like ball and then insert/press the ball in your ear, that's it.
This latter procedure only takes a few minutes (time for the silicon or resin or whatever it is to harden) then a counter-mold is made and finally a final piece is produced out of the counter-mold, then it is like 10 minutes of testing and removing (if needed) the excess with a small Dremel like mini-tool.
I am pretty sure that the cost of the whole operation, including materials and workmanship is below 40-50 dollars/euros and probably a lot of people would be willing to pay double that to have their earpieces (be them airpods or conventional wired ones) confortable to wear and "safe" (in the sense of not falling down at every movement) to wear when jogging or exercising.
Taking the mold as DIY, then send it to a laboratory and getting back your custom made earpiece adapter could be doable, but also a complete DIY kit could be used by many, it is not anything too difficult.
