This is a really fun make and a great sounding design! Printed in Proto-Pasta candy apple red and gold dust. I tried to capture the shiny/glittery depth of these filaments, but frankly the photos just can’t do it justice. I performed a trial run on the main body with some cheap filament first because I was concerned about register shift with such a long travel distance. About half-way through I did experience a couple of shifts, so I reduced the travel and print speed by about a third for my final run and didn’t have any further issues. YMMV depending on your setup. I typically print at 80mm/s on my machines, which is a bit on the faster side.
