While there are several other egg shaker designs on MakerWord, none of them were designed with little ones in mind (they are either too big or multiple pieces that could come apart and present a choking or suffocation hazard).  This print looks great in the new swirl or S-type tricolor filaments (shown in Amolen S-type black/red/yellow).

This egg shaker was modelled after the egg shakers common in preschool and kindergarten music classes at ~2.25" tall and ~1.58" wide.  The walls of the shaker are thicker than other designs, creating a durable model that is unlikely to break.

This model can print without supports.   Before printing, ensure there is a manual pause ~⅔ of the way up the shaker height (roughly layer 250 if using a .4mm nozzle with default layer height).  While the print is paused, drop in approximately ¼ to ½ tsp of rice (child safe, will not present a choking hazard if the shaker is somehow broken open) then resume the print to finish.
