I made this dogtag jig to fill my needs, i orderd a f1 and i like the fact that the dogtags face me when i engrave them. If you make two of them and glue them perfectly then you can do big batches real fast.
Load the file in your XCS software, check if my settings are fit for your laser and adjust them if needed. Start the project and wait till its done
Take the two pieces and glue them together, you can put it perfect on the score lines to have a masterpiece. Place something heavy on top after using glue for the best result. You could use some spray paint to make them more pretty.
When glued together you can use them in your F1 to do batches and make it more easy if you have two of them so you can refill and swap them.
