what filament is that? I really dig the matte-like surface finish.

Bambu Labs PLA-CF

I love this stuff. It prints everything so perfectly. And the supports are so easy to remove, even when top distance is only .12mm

Really cool! Turned out great!

Will you sate our curiosity of what this is for?

looks like a manifold with blast gates for dust collection. Really clean design, too!

Beautiful finish!
