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.
