3D Printed Dog Bone with Treat Pockets (TPU)

This is a flexible 3D-printed dog bone, designed specifically for TPU printing. It works both as a chew toy and an interactive treat toy, helping to keep dogs engaged and mentally stimulated.

The bone features four integrated pockets for hiding dog treats. Two of these pockets have a through-hole, allowing scent to escape and encouraging your dog to work for the reward.
Tested in real use — our dog absolutely loves it.

Scaling & Customization

• The model can be scaled up easily

• For larger dogs, it is recommended to:

  • use more wall lines (3–4)

  • optionally use stiffer TPU (e.g. 95A)

This allows the toy to be adapted to different dog sizes and bite strengths.
