Various dog toys - no supports

Here are some dog toy design. Pick the one you like.

Probably for medium to large dogs, but you can scale them for smaller ones.

The nut and the ring are in use for a couple of weeks now without any real damage.

Print instructions:

At least 6 walls (more is better)
At least 7 top and bottom layers (more is better)

0.2 layer height

15% Gyroid infill

Only print in TPU.
TPU 95A / 95A HF (print profiles for 95A HF)

Keep in mind that dogs can chew hard, so keep an eye on the toy.

Once they've damaged the surface, throw away the toy.

Wash the toy regularly because the layer lines can hold and cultivate bacteria.

Use at your own risk.
