Stuffable Dog Chew Toy - No Supports - TPU

I wanted to make a 3d printable, no-supports version of the famous stuff-with-treats "Kong" dog chew toy. I used TPU for the chewiness factor, in addition to the good layer adhesion--the last thing i want is this thing to shear/delaminate into tiny bits during normal use.

The file is scaled to the 'large' size of Kong, which is listed as appropriate for 30-65lb(13-30kg) dogs. Please use common sense and supervision when printing toys for your dog. I am not a veterinarian, engineer, or dog psychologist--just a guy with Blender, a dog with ADHD, and some TPU filament lying around.

FAQ:

"Is TPU safe for dogs to chew?"
-https://3dprinterly.com/is-3d-printing-safe-for-pets/#Is_PLA_TPU_Safe_for_Dogs

"PLA & TPU are safe for dogs and have been used as dog toys for many years. IHeartDogs talks about the AgriChew™ which is made out of TPU and has some serious durability as a dog toy.

The perfect dog toy wears away over time and a good TPU dog toy can last several months. The good thing is that TPU dog chew toys don’t come off in large chunks which would be dangerous, rather slowly wears away over time.

I wouldn’t use PLA as a material for a food bowl to eat out of, because when it is printing, there are tiny holes being created where bacteria from food can grow. PLA is also quite brittle and easy to chew through, so I wouldn’t use it as a chew toy."

"How do I clean this"
Warm soapy water. Dishwasher is a possibility, but depending on the material/dishwasher, you could end up with a melted chew toy, so dishwash at your own risk.
