I’ve printed similar objects with a different colored PLA, but I ran out of it and switched to this.
Is it possible that this could be influencing the outcome?
I have tried reducing the printing speed by 50%, but this did not seem to have a significant impact.
Isn’t this kind of a torture case for 3D printing? The higher you go, the more the part itself is an unreliable surface. Even in subtractive manufacturing, any weird sticky-outy bit with an extreme aspect ratio is prone to getting snipped off to become a separate piece.
Print two cylinders half this tall. Or print one piece flat along the board. Or buy a plastic dowel.
