Using Open SCAD you can quickly enter your dogs name and your phone number to create a flexible tag that can be worn on your dogs collar. 

Very easy to use Open SCAD software and you simply click the STL button (once you have added your dogs name and phone number and selected the size you want) to create an STL file and then print in a flexible filament of your choice.

I use a TPU such as Flexfill and change the color at the layer of the text, although single color tags still show the name and phone number just fine.
