The original was simply a lump of plastic. Injection moulding,
I'd guess. If a 3D printer can't make the same and as strong,
not much point other than as a toy.

Some can. You used the wrong plastic, as well as copying a flawed design.

I didn't make them. They were made commercially. By a specialist in such
things.

Who clearly used the wrong plastic for that particular item
or was too stupid to realise that he should have used metal.

Given what they cost, should have been the strongest plastic on the
market.

Doesn’t mean that he used that, or that it is adequate for the design.

The design is indeed flawed. But if it gave a few years
use in practice before breaking but much shorter with
the printed one it's fair to say it wasn't as well made.

Yes, but that may just be because currently plastic isnt what
should have been used for that part when it is 3D printed.
