We had a few of these get chewed up by our dogs so i modeled a replacement that can be printed. these are modeled exactly off of an existing figure so all dimensions should be very close to original. i shaved 0.1 or 0.2 mm off the diameter to make sure they would fit in all of the original toys.

I also made a version with some basic arms and fingers should you want a little more detail in your person.  both files are below. 

if you print with 0.12 layers, you can pause at these layer numbers for the color changes shown. 

247 - start of belt

253 - end of belt, start of shirt

483 - end of shirt, start of neck

Printed in PETG, 3 walls 15% infill regular supports touching everywhere. You will get a tiny neck brace of supports (probably not needed, but its very small), and the supports between the legs.
