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.
Hate to tell you but 3d printing Is not the right manufacturing process for the job … You may have It work out but thers no reason to melt pellet plastic into a somehow precise 1.7 mm diameter wire spool so that you can make a noozle go round for hours… Just buy a pipe … No matter what it will be cheaper more precise and sturdier …
I’ve been able to print similar models before with a different PLA and no issue.
