If it's not an original part, then don't use the reference code, it's as simple as that. Otherwise that's counterfeit.
To give more details, I hate it when nowadays you order a part online and you get a 3D-printed piece of shit instead. I've had several bad experiences, one being a wheel for a suitcase, when I put the empty suitcase up, the wheel broke off. Others are 3D-printed plastic to replace a metal bike part; really ?!? Even things like wood knife handle replaced by 3D-printed garbage !
The very structure of 3D-prints make it so there is a weakness in the layering; it'll break at the 1st opportunity.
