I've designed this maracas which uses filament poops to create the sound. You can print in mulicolor or even in a single color. I hope you like it !!!

Suggestions:

• Make sure your build plate is well cleaned.
• There is a pause during the printing, insert around 15 filament poops (depending on their size).
• Ensure that the filament poops are well positioned under the already printed part to avoid issues with the nozzle.
