Where from?
What material?
What fill pattern?
Where do you obtain the 3D files to send the printing people?
and can you edit them before sending?

So yeh, I’m coming to the point in my build where I’m needing to lighten things up, replacing my aluminium drive pulleys with 3D printed ones seems like an option I want to explore.
Wondered if aycone could give some good advice?
cheers. :-)
