Printed on an X1C using PLA Basic and Silk+ filaments. No supports or brim enabled and had no issues. Many thanks to the creator!

Printed using an X1C with PLA Silk+ filament with tree type supports. I had to use tiny pliers to remove the supports and tree type is easier than others to remove. Plays very nicely. Many thanks to the creator!

Printed using an X1C with PLA Silk+ filament with the fuzzy skin option. Only suggestion I have is to enable either the Brim option with the inner and outer type selected and the Supports option with tree type selected. Not sure if I'm doing it right as there may be a simpler solution I don't see as a beginner level 3d printer. Many thanks to the creator!

Using an X1C with transparent PETG filament and they came out really well using the fuzzy skin option. Its the kind of whistle you keep on a boat or watercraft. Printed a couple and going to use them as prize options for the kids at a Friendsgiving and its going to drive their parents nuts, love it :) Many thanks to the creator!
