Whistle with ball

Printed in either PLA or PETG. Once you load it into your prusa slicer split to parts don't split to objects so the ball stays in the same place. Now you'll have the whistle and the ball separated then add extra infill and perimeters to the ball settings and set them to 0% infill, and one perimeter with 3 bottom and 3 top layers ( the lighter the ball the better ). besides that print normally. Also use "Random" for the seam alignment or make sure it isn't at the choke point where its smallest. After the print is finished break the ball away from the whistle through the top air hole and it should work just fine.

( WARNING keep out of reach of children can be very annoying )

*Update V2 has lanyard hole an touched up.
