Remix of the reinforced dog tag design to make the tag double sided.
To make a printable model, edit the front and back text variables in OpenSCAD, hit F6, then export as STL.
In Slic3r I scaled the tag down to 60%.
To do a multi color print as I did, you will need to insert an M600 gcode to change filaments. To do this in Slic3r PE, you need to add custom layer change gcode to your printer settings. If the filaments need different temperatures (mine did) you will need to add a m104 command as well.
Below is the layer code that I used:
;bump temp for titanx
;return temp for abs+
Fornmfutura, Filaments.ca ABS
Black and Red
Scaled to 60%, add m600 commands to do a multi layer print.
