Simple. Easy to custom. Quick to print.
Customise and Create a Bone Tag for your dog!

Original File size is: 50 mm x 25mm x 5mm
And I model it in Rhinoceros for Mac (btw it's free)

1. If you only download and print the .stl file, you can be creative and just print a label and put it on the dog tag.

2. You can download the .3dm file and customize it.
   Just type your dog's name with solids and join it with the upper surface.
   What I did: Solid + Text + boolean union.
