Maraca
thingiverse
A simple maraca I whipped up for my niblings. Printed with the handle pointing up and the flat part of the shaker on the printbed. I made one with a 5mm wall thickness and a 2mm wall thickness. I used the "pause at layer height" feature on prusa slicer about when the main, cyllindrical part is ending and filled it with rice. You could use bbs or any other granular medium you wanted.
