I’ve been actively sharing my 3D printable designs on MakerWorld, and quite a few of them have gotten solid responses.
But almost every time I upload something, someone inevitably comments:
“Can you upload this to Printables too?”

And honestly, I keep wondering — why does it have to be on Printables?
Is it really about accessibility? Or are people just used to having one central place?

I'm not against Printables. But here's my perspective:

• I put effort into my models.
  Sometimes I design multiple versions, update them based on feedback, and even respond to requests.
• I choose MakerWorld’s Exclusive Program because it protects creators, even if just a little.
• When I decide to stick to one platform, it’s not out of malice — it's because of time, rights, and intentional focus.

But still, if it’s not on Printables, some people act like it doesn’t exist.
That mindset feels... entitled, and ironically anti-creative.

Then segue into your broader opinion:

This ties into the larger debate around open-source and platform expectations in 3D printing.
I’ve always felt that open-source became dominant because early printers needed it.
Users had to fix and improve things themselves.
But today, with more refined printers (like Bambu Lab), do we still need everything to be open and everywhere?

It seems like some openness is good, but expecting creators to be everywhere, all the time, with no limits — that’s not sustainable.
Not for hobbyists, not for small designers, and not even for innovation.
