Twin Tracks Module

Beautiful design. Printed without supports. I would advise very fine layer heights as with .2 it doesn't flow well. The manual recommends smaller layer heights on the funnel area only, but i would do it for the whole thing. I would say the documentation needs updated accordingly.

It printed fine, but trying to use it some of the paths were not steep enough and the marbles kept getting stuck.

printed perfectly

Very nice. I had some printing problems, I didn't understand if wet filament or anything else. Printing stops many times, the piece splits into layers and breaks. I repeat the print with a different coil, the same. I do the printer reset, repeat the adjustments and finally start again and get to the bottom. To try to bind the material better I increased temperature and reduced speed to 50. mm/s. The only problem, the finish is coarse and the marbles do not flow well. Done a thorough retouching with small grinding wheels for the nails and putting talc at the point where the marbles split into the path, the talc is distributed and runs better.

This is a really great track with lots going on at all times. It was a little tough to print since I missed the color change required comment, but I made it work.
